Advice PLEASE??

Ok this is a really long story but I need advice!

Me and my mom lived together in an apartment for a year since August of 2016. Signed a two years lease so the lease doesn’t let out until August 2018.

My mom moved in with her boyfriend leaving me alone with my boyfriend and I at the apartment. She offered us to stay there and her still pay rent (Super thankful)

So me and my boyfriend live alone in this apartment.

I’m pregnant. 20 weeks.

We are both students. I pay for my school out of pocket because I don’t qualify for financial aid. He uses financial aid.

He works at Winn Dixie making around $190 a week. I babysit making around $150 a week.

The only bills we have are car insurance and car payment. His bills come out to be about $400 monthly mine around $350 monthly. Then of course we still need money for future baby stuff, groceries, toiletries, and household items.

Here’s the problem.

He is a constant weed smoker. He smokes any chance he can get. He sometimes buys it and sometimes smokes with his friends.

Here’s the additional problem.

He does NOT know how to manage his money. He doesn’t buy anything for me, the baby, or the house. I had to beg him to buy us light bulbs today. Anyways he has $0 saved in his bank. I have about $400. And I’m working on managing my money better too.

Another thing is once the lease runs out this August, we have to get our own apartment. But how the hell are we going to make that happen? We don’t pay rent, utilities, or water right now. We aren’t buying diapers or baby things right now. And we still can barely afford the things we need! Thankfully, my mother has offered me, the bf and my baby to live with her and her bf for a year or so, so we can have more time to save. They have a side of the house that will are spare bedrooms!

But guess what. My boyfriend doesn’t want to live with them. He has a slight issue with my moms bf, he says he is too “demanding”. He says there cannot be two men in one household. He thinks that her bf will try to dictate our lives once we settle in. But I think it would be a great idea. I really want to.

So his money issues and weed issue is making me just want to save “fuck you, I’m doing what I want and taking the baby and moving in with them”

Anytime I bring up the weed thing he freaks out on me saying I’m trying to start another argument. (We argue A LOT)

I just need advice.... sorry if this is too much. I’m just so stressed and sad all the time.
