redskinsgg, im sorry that your hear, but you will meet some people and will get some much needed support. Soccerw has given you a few very good ideas to try.
I do have to ask this. Are you okay with living in an open marriage. Sounds silly to ask, but i was willing to do it at one point for my children.
If your not okay with it, have you clearly and calmly told your husband that you will not live in one.
If your not okay with it, why are you dating and having your husband over for dinner.
if you truly dont want a divorce in you mind, NOT YOUR HEART, then tell your lawyer to not file. Have him draft a separation agreement and see what your H does with that. its not closing the door on your marriage, but it lets your husband know you want to protect your rights and your stability.
What are you doing for you, to make you happy, to try and push your anger and hurt feelings at bay for a little while. What is your ME time.
Have you set any goals, what are some of them
Hang in there, you are strong and you will be able to handle this. You need to stop all talk about your marriage with your husband, right away. If he isnt ready to commit, and your not ready to live in an open marriage. WORK ON YOU. Be the best you that you can be, not for him, for you.
You will reach your goals, he will notice the changes, and if you shift his focus from the negative talk about your M and let him see you having fun and becoming the person you were when he fell in love an asked you to marry him, who knows, he might just realize what an idiot he is being.
