How to Handle Manipulative Relationships During Pregnancy?

I'm so miserable, ik this has nothing to do with pregnancy but currently I am 37 week's pregnant 21 years old... I got kicked out of my apartment I lived in,and family won't take me and bd isn't their for any support.

now I live with this 48 year old.man I knew for 2 years he's trustworthy and all but I need my independence he gave me my own room with a lock on the door and helps me out with money,me and him are strictly friends but his personality is manipulative and childish and he would ignore my calls and texts at times,or be upset cause I'm not watching a movie with him and rather go to my room,like for an example he wouldn't buy me something I needed and replied no. and I told him fine I'll ask my friend and he says now I'm pissed off, maby I'm just thinking to much,..

but he's sort of controlling and now I think he thinks he has controle now that I'm under his roof... we have the weirdest relationship and honestly I'm not comfortable I just want to cry all the time, he even asked me that I should think about giving my baby his last name incase something happens to me...

I'm so upset I feel like on lock down I have no car so yeah... my life revolves around him at the moment and I can't stand this dramma!

please God give me strength! I don't want to live with someone who is so manipulative again... I don't think its in my head but I question it because he's a nice\good guy. ugh...

sorry bout long story jus hard to explain ha.
