Help!

My boyfriend and I have been together almost a year we have a kid together (but we were seeing each other and having sex before we officially started dating so please don’t judge) I had our son in March and since then I haven’t felt attractive but he tells me other wise anyway we’ve been fighting here lately and I feel like we might be distance we haven’t really gone out since the baby was born I’ve been stuck in the house while he’s at work he helps a little when he comes home but still ask me what to why is he crying if I can do this that (not a problem he works most off the morning) but I’m so tired and don’t want him mad at me for being tired what do I do can anyone give me tips to feel better?
