I am new to this site and this was the first thing I have read after reading Q & A and such.
If you don't mind I have a story.
My husband and I were married for a little over eight years.
I am 55 he is 57. In his past marriage he had made it a way of life to see other women and have an affair ever 2 years according to his ex. His ex was having an affair for 2 years when they separated and divorced (her choice)They had been married for 21 years. My husband and I were married for 24 years he was 20 years older than I was but I did love him and tried to talk him out of divorcing me. He was seeing someone else and told me he had only ever been happy when he was with "her" and that he had never loved me.
I met my husband about two years later I had been a Christian since I was fourteen, he had just gotten saved after his marriage broke up.
He told me about his affairs with other women during his marriage and that he did not ever want to make that mistake again.
For over seven years he did not. Ours was not a perfect marriage and we did have problems as many married couples do. But we also brought out the best in each other and at times the worst.
I tell you all this to get to my point.

My husband was faltering at his job he got a set back because of something that was not his fault. I was doing very well at work and had just landed the greatest job of my life.
My husband is a corrections officer and was sent to work in our local jail, before he had been a shift supervisor. It hurt his pride very much.
The woman he started the affair with was visiting a prisoner. He had had many one night stands with her in the past but had not seen her in about ten years. They started calling each other, then going out drinking together when I was working(we worked different shifts)
I knew he was drinking but never suspected with another woman. Then they started getting physical. At first he was a new man in our bed, Making love to me in ways he had not done since we were first married. Then he started to turn on me. Yelling at me and telling me how horrible I was. I went from being almost perfect in his sight to a b---- in just a couple of months.
On our eight year wedding aniversary I was told he was seeing another woman. Since that time he has moved out of our home into another house we own with her. She will stay a while then leave and come back. She has spent her whole adult life living off other people (I am not saying that is your case at all just telling my story to try and help you understand).
My husband who wanted a divorce soon after I found out about all this(which was granted)tells me almost every day that he loves me and that we will be back together again. That he feels he is finishing up something that was started years ago.(that is a cop out)He tells me that he feels eventually he will get his mind straight and he will be home and we will be married again. He also tells me he holds me second in his heart with only his mother coming first. I know it sounds like I'm crazy but I do know this is true. God has directed me to stand in the gap and pray for my husband and has promised he will restore our marriage.
My husband tells the other woman that he loves her which is also true to a certain extent. He has ask her to marry him but only to get her to move back in with him. And in truth he may do just that one day but it will never work.
To him she is his last fling a part of his youth. I am his roots his security his past and his future and in his heart his wife.
I tell you this so you can understand things are not always as they seem. My husband tells me all about her and their relationship. He tells her he only talks to me about bussiness.

Please know as much as I hurt I tell you these things to help you. Your now "husband" has not told you the truth and his ex is probably waiting at home for him to come back. The ow in my life never sees where I talk to my husband, she does see the things he does for me. She does not see the nights I cry out to my God to restore my marriage. She sees none of my pain to her I am just an ex.
The Bible says "what God has joined together let no man put asunder" I know as does my husband that God truely put us together. No other woman, no judge, no lawyer, and not even ourselves have the right to tear us from one another and we will be together again soon. No one wanted either of us we were both thrown away so to speak we each prayed and God put us together "till death do we part" This was only after our other mates had went on with their lives.
