Back off from your Husband and work on YOU. Space is probably a good thing right now, even though it seems like exactely the wrong thing to do.
You can't MAKE you husband come back. He is not listening to you right now. His ears are broken:) Do not pursue him, it won't help. You are talking to a rock in the fog right now. Rocks don't talk, and what they might say probably isn't very interesting <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" />
Soooo.....
Let's focus on YOU, not THEM.
Take time to take care of yourself. It really will help. If you have extra money available, be a little selfish, and go out and "responsibly" spoil yourself a bit. You deserve it. I traded my own old car for a new one. I joined a fitness club, (excercise is the best thing you can do right now). I got a pass to a tanning bed. Taught my kids to ski. Got my first massage at a spa, I am learning Yoga. I read a lot. Here is a link to a book that I am reading that has been very useful, you can print it out.
http://www.meridianmagazine.com/books/020821bondsend.html Do things that make you feel better about yourself. Your husband is the child here. Be firm and loving with him, just like you would be with your children. Develop a strong, confident quiet attitude. You are a Plan A warrior !!! (great saying, I swiped it from someone else on the board)
Since you have kids, schedule a baby sitter sometimes and go out and have some adult fun with friends, or explore something new by yourself. Tell the kids that mom has a plan. This will comfort them a lot.
Send the sitter bill to your husband. If he won't pay the bill, then schedule time with him via e-mail for him to watch the kids so YOU can go do something FUN. If he doesn't show up then document it, and save it for court. Don't bug him or get mad at him if he doesn't show up or make time to watch the kids. No LB's.
Talk to other people. Make sure that anyone who could POSITIVELY influence your husband knows about what is happening. Don't just blab about it to everyone in town. The more light you shine on this affair the better. Telling others will empower you. You might even help your friends save their own marriages. I have had some of my friends tell me that because of what is happening to me, they are taking a hard look at their own marriages. This makes ME feel really good!!
Be patient. This will probably take months. I am three months into this now.
No, NO, NO!!! LOVE BUSTERS....I learned this the hard way, and it cost me a month of bridge building with my WS. Put a smile on your face and be the best person you can be. Do what is right no matter what. You are a wonderful person, and taking the higher moral road will help you through this. Your husband may not show it, but this is hurting him also.
Keep the faith, he will probably come back. Either way the time and commitment on your part will be a positive thing.
Treasure each day.....
