Tubes tied BUT regret

Am I crazy for wanting another baby? I got my tubes tied after an emergency c-section with my daughter (3rd baby) because my then husband REFUSED to get snipped. Since then my ex-husband and I have separated due to his narcissistic tendencies, alcohol, physical abuse and even sexual abuse. 😔 I’ve met someone great who literally loves my 3 kids as his own but I know he’d love to have one of his own too and I feel guilty I can’t do that for him. I’ve thought about a reversal but we know that’s expensive and it’s not even a guaranteed thing. Am I crazy for praying I may naturally become pregnant?! I’m only 24, got my tubes tied at 22! But back then I felt I had no other choice since husband then wouldn’t and I’d fallen pregnant with our others on birth control. 😔 Yes, I know I’m young, no I’m not saying I immediately want another child but I wouldn’t be upset if it happened. Anyone else in the same boat? And positive experiences? Thanks for reading!
