Hormones or is it weird

I’m 34 weeks pregnant and I have an almost 2 year old. My kids dad and I have had a very rocky relationship these past two year, though we were planning on him staying with me these last few weeks of pregnancy and then moving in together. He’s been around maybe 5 times these past two months because he has another son he gets once a week and he lives with two er nurses/doctors. And he also started drinking heavily again. With that being said he stopped drinking and will be drugged tested by his work every week now and if he screws up he will be fired. So I don’t think the drinking will be a problem for a little bit. He also said he was going to wait to get his other son for a couple of weeks so we didn’t have to worry about me testing positive for the virus in the hospital. He stayed the past two nights and isn’t coming back tonight because he said he needs to get sleep and cant get good sleep here. (My is not a great sleeper.) and he is also continuing to get his other son once a week. Am I wrong to be upset about this. Should I not be concerned about him getting his older kid? Or be upset that he isn’t coming back because he needs sleep? I barely sleep anymore because I’m so uncomfortable and my oldest keeps me awake. I just feel alone.
