Husband continues to disappoint (sorry if its long)

I'm not sure how to really word this but my husband is the best(second to our daughter) and the worst thing that's happened to me. We never really had the best relationship before we got married but decided to work on ourselves together.

We ended up moving in with each other and a couple months later I found out I was pregnant. He was always there for me, picking up my vomit from time to time and always making sure I was fed and mentally okay. Then our little bean came and this kinda turned around

He would never really help out with our baby and me being sleep deprived and mentally on the edge it was hard. I went to working (at my job) till the day I went into labor, to taking care of him and our baby the day I was discharged. I'm not too sure if he ever understood how it's been for me especially with my new prescription of birth control.

My mood is constantly changing and I often find myself in this funk where I feel like I'm still in my postpartum depression but im not. I was never able to return to work due to us not being able to find someone we trusted to watch our daughter. He constantly rubs it in my face stating that he's the only person making an income and that because of that I should have meals prepared for him 3 times a day, house cleaned (with a 9 month old who is walking and constantly making a mess) and being able to do whatever he asks when he asks.

I figured it was just due to his background in the military and him being raised in a machismo environment.

Going back to us not having the best relationship before marriage, he would cheat on me and I would do the same (stupid kids who didn't understand anything other than revenge). I always have that gut feeling that something is going on, then finally my doctor called me stating that I had chlamydia.

Me knowing that the only time I ever get to leave our house is when I go grocery shopping or do laundry at a relative's house, I couldnt do anything. Especially with our 9 month old and my on and off depression.

I went into this rabbit hole of trying to figure out how I could have gotten this, like hygiene, UTI's and well sex. But everytime I would try another option it would all lead back to the same thing. I wasn't able to get any answers from my doctor since "he'always busy" I would call everyday and they would always say he'll call but never did. It took me two days to finally bring it up to my husband (due to me being scared of him) and it surprisingly went well. He still hasn't gotten tested yet, and won't have any sex with me. (Which I'm fine with till he gets treatment) but he doesn't even tell me he loves me and won't touch me.

I'm not sure what to do, and hopefully someone stayed around to actually finish reading thia
