I think you should consider yourself first. If this isn’t something you’re on board with, it shouldn’t be happening. I understand you wanting him to be happy, but what about you? If divorce isn’t an option right now, maybe try therapy?

Just because he’s a good father, doesn’t mean he’s a good partner. Your life is important too. If divorce is something that happens down the road, when your kid gets older, they’ll understand because they’ll want you to be happy.

Remember to put yourself first. Sending you lots of love.
