I’m so sorry for all that you’ve been through, Laura. You’ve been getting a lot of great advice that I won’t belabor, but I will share that from my own experience, trauma on trauma on trauma really does need to be directly addressed. It doesn’t quite work to just get out of the traumatic experience and soldier on. Trauma alters us profoundly, and you’ve had a lot of it.
You said that you don’t think your ex would ever cheat on you again. Gently, wayward behavior is so many things beyond just, well, the cheating. It’s the lying and the entitled mindset and the manipulation of self and others to engage in all of the unhealthy behaviors and it’s the sneaking around. In order to be a safe partner again, a WS has to really figure out all of their unhealthy, dysfunctional behaviors and stop engaging in them permanently. They have to change so much and work so hard to do that.
Your ex doesn’t seem to have gotten there. You had sex, so he felt entitled for you to be his again. Please let that sink in that he felt that sex entitled him to ownership. He accused you of basically giving that to him by sleeping with him. This is not a healthy attitude towards a relationship or towards sex. It is an entitled mindset. Remember that this is the person who felt entitled to stay married to you and sleep with someone else at the same time. He felt ownership of both of you, apparently.
He may have gotten better over the years, but he has not eradicated all of his wayward entitled thinking. When you didn’t immediately acquiesce to his desire to rekindle the relationship, his response was to pressure you and try to make you feel guilty and responsible for HIS feelings. That is also manipulative and wayward behavior. After all that he put you through, he still doesn’t listen to your feelings and respect them. He feels that he has a right to change your feelings instead of accepting what you want. What he wants is still the most important thing.
You don’t have to think he’s a horrible person and not your friend to recognize behaviors that are not respectful of you as a person. He is certainly not the only self-centered, entitled person on the planet. But you really need to think twice about whether or not you would be happy with someone who doesn’t respect your needs, and you should really do some exploring about why you so easily fell into second-guessing yourself and accepting responsibility for his feelings. You didn’t MAKE him feel entitled to having you back by sleeping with him. He DECIDED to feel that way because of his attitudes about what he is entitled to.
These are the types of things that should be explored with a really good therapist because they are the key to keeping yourself safe in your relationships, setting better boundaries about what behavior you want and don’t want in a partner, and becoming healthier and happier for yourself first instead of trying to do what will make someone else happy. We all have struggled with one or another of these issues.
Clearly, every BS on this site chose a partner that ultimately felt entitled to cheat on their spouse, lie to them, and deny them agency in their own decisions at some point. These are issues we all have to explore and address sooner or later in order to move forward to a better future.
I wish you peace and strength as you move forward, Laura. You have been through so much, and you deserve that peace—whatever form of it YOU want.
