Panic or not ? Where is my relationship going?

Sorry for the long post and thank you for reading ❤️

It's hard to put it out here but I need advice.

We just had a baby 4 months ago, during pregnancy we had still lots of fun having sex even better than before, until I couldn't because of preterm labor which wasn't really an issue cause we already stopped at that point ! So far we're okay.

Comes 6weeks after birth, he still doesn't really want anything, I asked him a few times but nothing happened. It was the holidays season he works a lot plus new life with baby, okay he may be tired.

Finally at 8w pp we get to Do the deed.

Since he still has no drive !

I asked him if it was me being out of shape he said no.

He is not romantic, or doesn't really engage anything spontaneous.

I am currently a SAHM, I do work partially but he still complains often when he comes home if I didn't do something like I should have on whatever or make little comments which lately hurt me a lot because my baby needs me 100% . He also thinks because he is the one who brings money that I should pick up his mess after everything he does🙄😔, which I ask him each time to put things back where he took them from at least.

I'm really easy going and really loveable, always showing him love and attention but I can't anymore.

Im tired of trying, im tired of asking, im tired of hearing comments and not have sex on top of it !

Im not a bitchy and naggy person but I think he made me this way now.

I'm getting scared of where this is going, I've talk to him and he is working on his bitching but still stays on his stupid game all day and when we go to bed instead of using that precious time when baby is asleep.

Im getting very frustrated and tired of explaining.

I used to be very thin and driven and now I can't loose weight at all, I'm trying hard to keep breastfeeding while fighting my low supply ..

Sorry for the rant, he still has great sides, he is doing good as a dad and I appreciate it but I don't know if I should just stop trying and let it go to crap at that rythme or if there is another solution to not get this relationship going to crap.

We do love each other, we do want to stay a family but I'm just sick of fighting by myself for it.
