Opinions please...

I’m trying so hard to be happy... I’m pregnant so I find it even more hard to have these thoughts. Part of me believes I’m losing feelings. Would rather be alone then with him, most days I’m just in the bedroom while he’s either at work or in the living room. Notice that we argue over literally the smallest things. Sex life is pretty much non existent. So what would you say, am I just not wanting to admit it to myself that I’m actually losing feelings??
