E.W.
M.,
Twenty years ago, I married a man with 3 daughters. The oldest lived with him at the time and the youngest came to live with us a few years later. The middle one always only put up with me just when she had to and put forth no effort. Even though my husband had been divorced for 3 years before I even met him, I stole daddy from mommy.
It was never an easy relationship with my husband's ex. Don't sweat it that he has a history with her, you can't change that fact. If she is a nice person and trying to make friends with you consider yourself lucky. For years I hd to play the go between on the children between my husband and his ex because they wouldn't talk. I finally blew up at the both of them one day and put my foot down and forced them to talk about thier kids again. (When I get riled, not to many people will tell me no to what I want!)
There were difficulties all those years, I had to do my best to try to make friends with her because of the children. Children go through so much when parents divorce. They are the first priority. Not your feelings, your husband's feeling or his ex's. You have to learn to work together with each other. I would suggest that you do your best to have some sort of friendship with the ex. Siimply for the fact that it does make life so much easier when you have your step son. When he is in your house, you make the rules, not his mother. Beleive me kids will do thier best to turn the grownups against each other if they are not getting thier way. There are so many stories I could tell you of what my step daughters did to me, some of them would curl your toes. They are all grown now and have children of thier own. I am known as Nana. When my first grandson was born, he had 5 grandmothers and my oldest step daughter wanted a special name for me since I raised her and helped her through a lot of troubled times. My husband's ex is gone now, she passed away a year and a half ago. She and I were friends from time to time, had our differences but she was also easily swayed by her kids and I had a lot of trouble with that. You will just have to ride it out. Your husband will be there to help you but there always will be something that you will have to work out with her.
If you feel she is responsive to listening to you, then try to talk to her about your step son and how you will handle discipline issues in your house. Make sure you and she are on the same page so that the table can't be turned on you. Always always always, keep the lines of communication open if you can. This will not be easy and it will probably take more work on your part than anyone else's, but it will be worth it when you can have a fairly peaceful life with your husband and you can say when your step son is grown that you helped to make him the man he has become.
I wish you luck and patience. Heavy emphasis on the patience. You can send me a private message if you need to talk.
