Ever regret leaving your husband?

Please don’t be mean, I’m very torn on breaking up my family and want advice.

Has anyone here gotten divorced from your husband and regretted it? I’m so torn because I know I am gay, but I don’t know if I’ll ever find a relationship that checks all the boxes that he checks (minus the sex/romance aspect) like we get along great, have kids we raise well together….i guess I’m wondering if it’s the “grass isn’t always greener on the other side” Will we get divorced and I’ll realize I had it good with him even if I’m not sexually attracted to him?

I guess a question I have is…am I bi (which is what I’ve always considered myself) and don’t want sex due to life stressors and pain with intercourse, or do I not want sex because I’m just gay and that’s that (and sex hurts because my body/mind is essentially rejecting hetero sex)

I’m scared I’ll get a divorce and see him with a new woman and think “well shit I made a mistake”

or

will I have a great relationship with a woman and we will both be happy in the long run. I’m breaking his heart so I just wanted advice from others who had been in my boat.
