I don't feel attracted to my husband anymore

We've been married almost 4 years, have a 14 month old and a second baby on the way.

For the past year I've felt like I've almost fallen out of love with my husband. I appreciate that he works hard for the family, but I've also felt wayyyy more annoyed with him than loving towards him. I don't ever want to have sex anymore and when we do it's strictly because I feel I owe it to him, and when we do I just fake it until he is done. I don't enjoy sex with him anymore.

I also don't feel like I find him that attractive anymore? I don't think he is ugly but i think that since I've felt more annoyed towards him, I don't want to kiss him or hug him and all physical attraction I had towards him is gone becuase all i see now is being frustrated with him. He has even noticed when he tries to kiss me, I pull away or push him away.

A lot of days I'll take my baby to go to a park or to my moms just to get out of the house to be away from him. I get annoyed he wants to touch me all the time too. I'm not a sexual person but I feel like I'm even less sexual now.

He isn't abusive by any means, and nothing major has changed besides having a baby. He does work hard for the family while I stay at home, so I'm not sure what happened. I don't think he understands what I'm feeling either. I've tried to talk to him about it but I'm not sure what the best way to bring it up is because I can't pin point an exact turning moment.

I do feel exhausted. I do 95% of the housework, I'm a SAHM, do all the cooking and I haven't had a moment to myself in over a year. My baby is a mama's boy and won't let me out of his sight for more than 30 minutes. When I do get a break away from my baby it's so I have to cook or clean. I also don't feel like my husband helps with the baby as much as he should. He does help but he never offers to watch the baby while I have time for myself, or do some of the chores etc.

So maybe that is a big part of it? I just feel annoyed he doesn't wanna be helpful?

I don't want to call it quits unless I know for sure This isn't a stage that I'm just going through because of the adjustment of having a baby, or something else.

I just can't get over all the little annoying things he does and they just add up until I'm sooo annoyed I can't think straight.

Is this just what marriage is after awhile?
