What state are you in? If she isn’t on her feet and she divorces you, then she won’t be able to go anywhere for a while until the child is capable of self‑care at best. And you’ll be paying for everything: house, food, and doctor visits. If she has a bad history and didn’t have a career before the new child, then you may have a leg to stand on. But 90 percent of states favor the mother as full‑time caregiver in a split‑up. Once a liar, always a liar. It’s toxic, I know, but you have to do what’s best for your child. If you keep flopping like a fish trying to get to the water then flop the wrong way you’ll end up wasting lots of time. Trust me, I’ve done the same thing you have. I broke it off, but we weren’t married; cute, she wasn’t emotionally stable for marriage, just wanted it within three months. Idk, three months is nothing it’s a season. But she got bored ’cause I was working all the time. Meanwhile I was covering the bills while she wasn’t providing in the relationship before my first was born.
