Difficulty: Moderately Challenging
Step1
Recognize your value.
This is the most important thing to keep from getting jealous of your husband's ex-wife. You have him now. You are the most important thing in his life and he comes home to you every night. Remember these things.
Step2
Try to understand the ex-wife.
If she's single, it can be especially hard for a woman after a divorce. It only makes it harder on her when he finds a wonderful, beautiful woman like yourself before she has found someone new. Try to feel for her, and you become the better person.
Step3
Trust your husband.
Nothing will work in your marraige if you don't trust your husband. If you do then you can let him be as nice to her as he wants. You know that he's not even thinking about leaving you for her, and you have no reason to be jealous.
Step4
Don't take it out on the kids.
If you have stepchildren, the divorce of their parents is a lot to take, and depending on their age could stick with them forever. If he seems to side with his kids over you, he is trying to make up to them what he took away by ruining their home. The kids didn't make all the bad things in your life happen, and their life is probably pretty tough, so don't take it out on them.
