If you read several of the posts on this site you will see at least two very consistent themes. 1. People who are in committed relationships desperately want them to work and satisfy their longing for connection, in spite of the foolish and hurtful things they do to each other and 2. People in committed relationships accept behavior that is completely unacceptable. You would never have put up with your husband if he said at the outset of the relationship “I want to keep drinking and seeing other woman while I’m with you. Is that OK?” He would never have married you if you had said “I want to have an affair once in a while. Is that OK?” Both of you would have said no and looked for a partner who met your needs appropriately and consistently.
Yet that is what you are both expecting to put up with now. Both you and your husband have made mistakes and hurt each other, both of you have done things that the other person finds unacceptable and you both have some desire to resolve these issues and create a satisfying relationship. But neither of you can continue to have it both ways. Both of you must stop loving and hurting at the same time.
Now is the time for both of you to grow up and be mature about your relationship. You must tell your husband that you want to re-establish the marriage but on new terms. No drinking and no contact with his ex-wife. In return you will end all of your affairs. Maybe he needs to change jobs or you do, or both. You must do whatever it takes to make your marriage relationship the priority. You will now operate on a new basis – trust, honesty, joint agreement etc.
You might think these standards are tough but it’s exactly what people expect of a marriage, nothing special or more demanding. If you think back to when you first got together each of you was on your best behavior and did just what was required to make the other person happy. You fell in love and lived happily for a while. Then gradually reality set in. He offended you, but you let it slide and vice versa. So it became possible for each of you to hurt the other person significantly while still calling it a marriage.
So now there is no marriage. He’s gone and wants to “check the scene”, you want to restore the marriage but on new terms. You cant make him come back, you cant force anyone to do anything. It must be a completely voluntary decision as it was when you first married. Only this time neither of you have blinkers on. Now you really know what for better or worse means and you either accept that or not.
So plan B is the right way to go for both of you. If both of you can agree to restore a monogamous, exclusive non-abusive relationship, where you both work hard to minimize hurting each other then there is every chance that you are the best possible match. But if one or both of you can’t make that commitment it’s over.
That doesn’t make the grief, loss and pain any less but it makes it less confusing. Both of you have to set and stand by the standards you are willing to accept in the relationship and stop settling for second best. It will hurt if he won’t come around but at least you know where you stand and what you will and will not accept from a partner. You can hold your head up knowing you did the “right” thing, a little late perhaps but better late than never. Whatever happens it builds your self esteem knowing that you won’t settle anymore.
I hope it works out for both of you. Good luck.
