My baby daddy Jonasi

I'm a 31F currently dating a a 35M.we started out very casual admitted he has 2 kids by different mums. Cool no problem! After a few months though BM no 2 comes to me as a woman, I confront the guy and says she's just finding it hard to let go. At this point in confused since she claims they live together but also I'm at his like 4/7 times of the week. Fast forward I get pregnant and all is well till I go through the holy grail!

MF is cheating like on a universal scale I'm beyond shocked. So I stay silent and just ask if we end the relationship since clearly. Anyway dude insists that this is where he wants to be.

Now my concern is he's very intentional but also very unfaithful !
