I will go to the MC with him and I hope it will be good for us.
lyndam - first things first. You need to move your posting to the General Questions II forum where there is a much higher rate of posting from others so that you can get as much support and advice as possible.
Second, having read your post I have to agree, sort of, with one thing that your husband has said, you are appearing to be weak and whiney. That is very understandable to me, because having been a Betrayed Spouse I know the emotional shock you are going through.
Here is what I see.
You have had 6.5 years of a "wonderful relationship."
He has had 6.5 years of "free sex" and no commitment.
You have been married 4 months.
He has never been married to you.
He was married before.
Why did he divorce the first time?
He has children.
He is NOT a father.
You want children.
He does not want children.
Question: Are you so weak and insecure that you will take the "garbage" as your filet mignon?
I understand that for whatever reason YOU want to save your marriage. So try Marriage Counseling and see if it helps. Keep a close eye on what is said to him, his responses, and what he begins to make changes in.
I am NOT convinced, personally, that this marriage is worth saving because you've never HAD a marriage. YOU have, but he has not. The BASIS doesn't seem to be there.
Certainly NOT the basis that can withstand an extended separtation (overseas work environment) because your husband is NOT "into" denying his own wants for sex and honoring his wedding commitment to "forsake all others."
I am convinced from what you wrote that his "I'm sorry" is nothing more than he's sorry he got caught cheating. He is NOT sorry in a repentant way.
So let's get practical for just a minute. This is going to require you to stiffen your spine, accept that the marriage already ended when he chose adultery BEFORE, DURING, and AFTER your marriage.
"saying he was pushed into an A because I am unreasonable and "angry" with him and have been for the duration of the relationship. " This is typical Wayward Spouse attempting to "gaslight" you and make YOU the problem. Lyndam, here is the absolute truth that YOU must know and understand. There is NO excuse for Adultery. The FAULT for Adultery is completely and 100% on the Adulterer. They own it 100%.
IF there were relationship "troubles" two things should have happened.
1. He should never have married you.
2. He should have talked with about the perceived problems, and with a PRE-marital counselor, before CHOOSING to engage in adultery with another woman.
"He goes mad and then starts the blame for his indiscretion saying it is exactly this reason why he went off with OW." NO, this is his "excuse" for cheating. He doesn't want to accept responsibility for HIS choices and HIS actions. He wants to make you the "bad guy" in this so he can either "justify" the unjustifiable or CONTROL you so that he can continue doing whatever he wants to do regardless of its impact on you.
"I went to bed crying and he scolded me and said it was pathetic and I needed to grow up and stop being a child. He said he had heard it for 3 weeks and was sick of me being a victim. He said I had to be stronger and to be able to face lifes ups and downs..""3 weeks?" He was nailing his bimbo for 7 months, and THAT's not pathetic?
I'm sorry lyndam, but he has NO concept of love, much less care for you. OF COURSE he doesn't "like" to see the emotional devastation HE has caused, because it makes him have to see that HE is the cause and his choices DO have consequences on others. He wants to deny that and wants to believe that he can do anything he wants and it's "just the ups and downs of life, so get over it."
"He wants me to shut up and get over it or we will not move on. Is he right?"Yes and no. He is right that he wants you to "move on," BUT only on HIS terms. Marriage is 100/100% deal, not a 50/50 deal like so many like to think.
He is right that HE wants you to "shut up" and forget about the single biggest betrayal one spouse can do to another spouse because he thinks HE has the right to do anything he wants and you only have the right to "sit there and take it."
He is right that for 6.5 he has been able to mainpulate you and control you and fool you into thinking he was a "nice guy" and "marriage material." NOW you know the hard truth, he is a USER of people, not a lover of people.
HE is intensely selfish and only concerned about himself.
It hurts to know that you could have been so naive and "blinded" by YOUR love for him that you wouldn't let yourself "see" the ugly side of him.
I am equally certain that during the previous 6.5 years before your marriage that all was NOT always "peaches and cream." I am certain that with his selfishness there were many time when you "saw" the real him, and then chose to ignore it, excuse it, forget it.
So he is expecting more of the same now.
Is THAT how you want to spend your married life?
Make it CLEAR to him that you will go to counseling with him because you love him, BUT he is on notice that unless you see him facing and dealing with HIS problems, you will give him his wish to be "free of you" and "free of the restraints of marriage" on his selfish pursuits.
It IS time you "got over" the "weak-kneed spineless clingy I'll do ANYTHING to remain married to you, you wonderful hunk that I MUST have in my life!" sort of wimpy behavior and STOOD UP TO this poor excuse for a man and disaster of a marital partner. Make it CLEAR that he VOLUNTEERED for marriage, with all of what it entails, and that his choice for Adultery was his and his alone.
Personally, I hope your counseling has good results, but I am very pessimistic. As such, I would also suggest you contact an attorney as soon as possible to draw up divorce papers. It is TIME that he understood marriage is a "two-way street" and that it is Exclusive of all others, so if he doesn't come around, be ready to cut yourself loose from this person.
By the way, SAVE all documentation you have of his affair. You need to divorce for CAUSE if you choose to go that route.
God bless.
