Advice please!

Okay guys, so my “baby dad” (I hate that term) isn’t really into the pregnancy and I don’t expect him to be as excited as me but he shows no care or emotion and it bothers me soooooo much. At first he wasn’t team baby at all and over time he’s changed but very little . I already set up our son’s nursery but everything baby related I end up having to do on my own. I set up the nursery, put together the crib and bassinet, bought the travel system and set it up, even bought the clothes and go to doctors appointments alone. I know right now with the pandemic things aren’t as easy but he doesn’t even try, then he’ll lie to his family and friends and act like he’s an active part of my pregnancy and he’s not. I don’t know what to do anymore. I told him to leave and tried to kick him out, gave him the option to leave if he doesn’t want anything to do with me or my son but he swears he wants to stay but never shows it. I’m at a loss here. This is my miracle baby , I have PCOS and was told I’d never have kids on my own naturally after five years of trying with no success. Now it’s like I can’t enjoy my pregnancy and any time he sees me enjoying any of it he finds a way to put me down about it or bring me down. What do I do? I’m gonna be seven months pregnant tomorrow and this baby is going to be here soon. I don’t want that kind of negative energy around my son at all. Any advice would help at this point.
