In love with someone else

Does the ex know you are with someone else? If he does, I would really advise to be careful with him.

Such hardly ends well even after you have given up a complete family unit to go and "try" with him.

For your current partner, isn't there no way for you to work anything out? What was it like in the beginning before falling pregnant?

I know a lot changes for many once pregnancy and baby gets in the picture.

See if couple's therapy can help? There's a lot you can do to rekindle love if it was there at the beginning

Do you feel the Connection or you just want an excuse to leave your partner?,I don’t think is a good idea jump from another relationship to another. Maybe you should take a break from both guys and think about what you want for you and your family

I agree with Rosy. and even if couple therapy didn’t work and genuinely nothings helping, i still wouldn’t leave just to be with your ex. leave to find yourself! be single for a while and fall in love with YOU, not someone else. a lot of the time we want our ex back because we miss how we felt during that time, not because we actually miss them. so find that happiness and spark within yourself, by yourself x

An ex shouldn’t be meeting your kid any time soon just because u want out. Me and my husband are separated now. We were together 8 years and he has been with a girl for a few months. She will not be meeting my daughter til they’re together a year, she’s met my son. He’s a baby and I wasn’t ok with it honestly. I still live with my husband until we can figure out living separately. But my point is, don’t stay just because u don’t wanna break up your family. If you’ll be happy separated then leave.

I would ask yourself if you have feelings for the ex, or if you are just unhappy in your situation and the ex is offering an 'easy out'.
Our brains love to romanticise things and our fantasy is normally way better than the reality. The grass really isn't greener
