I feel extremely selfish...

So lately I've been feeling like it's just me, baby, and our 2 furbabies. My husband recently started working his 2nd job which are at night on Fridays and Saturdays. Meanwhile he works from 7 something in the morning and doesn't get home until after 6 due to having school for his job right after. Then he also is working on his online brand after that so he's mainly on his laptop. During that time he does do diapers and I can get a shower in. I work part-time, but I'm also up all night with baby because I feel shitty for waking him up due to working so much. I want to be able to spend more time with him, baby, and our 2 furbabies distraction free but I feel bad about it. As well as feeling horrid on Saturdays due to being up all night then having to get up early for work because I don't want to wake him up due to him getting off at 4:30-5:00am knowing he also has work and school the previous day. I just feel drained and kind of alone which makes me feel even worse because he's trying to do what's best for us.

And yes I'm currently trying to find a better paying job so I can try to talk to him and explain more that money won't be a problem.... I just feel bad in the meantime and have no one else I can tell or atleast talk too.
