I’m sure this question has been asked, but I am having a hard time accepting the fact that I won’t be able to have sex with her, but that some other guy will

She broke the trust in our relationship through substance abuse, and for me and my kids sake I am leaving her. I don’t really have any other option at this point.

Thing is, I feel like she is forcing my hand in leaving her because of her poor choices, and that is frustrating because I don’t “want” that.

We had a great sex life, and I am giving that up for mine and my kids to be happier.

It just sucks because I want the intimacy and I must willingly give it up.

Can anyone relate?
