Hello Daisy1122: I'm sorry you find yourself in this most difficult situation.

About all I can say is that, from my perspective, people don't change a whole lot. What you have experienced over the past 13 years is probably what you can expect to experience more of if you stay with your husband. I can't tell you if what you're doing is right. But you certainly do have a right to your feelings. Is it selfish to leave? I don't know... maybe / maybe not. But one can only tolerate so much. And if you've had it... you've had it.
I see this is your first post here on PC. So... welcome to PsychCentral… from the Skeezyks!

May the time you spend here be of benefit. Hopefully coming here to PC can be of some comfort & support.
