Not sure I want 2nd baby now

I used to always say I wanted a big family with 4 kids. Now that I’m a ftm I can’t imagine even having another. Not because babies are hard bc we got a super easy one (so far knock on wood!!) but because I can’t imagine having to share my love and attention. Also knowing how much money we’ve been spending, we are pretty comfortable financially now but if we had a 2nd kid we’d need to add on to our house and idk I just can’t imagine. My relationship w my husband had changed so much too. I love him so much but he doesn’t help much with the baby. I find myself having to ask him just to watch her so I can shower or go to the bathroom. He’s helping out in other ways (doing the dishes etc) but if we had another omg I feel like it’d be terrible. Anyone else feeling this way?? I’m hoping it’ll change but 🤷🏼‍♀️
