I never posted anything like this before ever! ... but I feel so lost.. any advise would help ...

my baby is 1yo and Jo (fiancée) and I have been having some many issues from 1 year after we started dating. We just don’t get on and argue a lot. We do love each other though. We know that for a fact. We bought a place together and decided to get pregnant.. but ever since baby is here, pretty much we got worse at communicating with each other. I mentioned separating but he won’t have it. He’s right when he says we should try harder for our family as we love each other .. but after 5mins of talking about this, we are at it again. I think our baby is also noticing the arguments, she’d cry sometimes in the middle of one. I know we need to try therapy, but we don’t even have the time for this. We both work full time and hardly have spare time to do much. And also no family to babysit etc.. the struggle is real ...
