Cut throat

I've been having doubts about my boyfriend that I love so much he's amazing but we have been fighting a lot over stupid shit and I don't know anymore if he's perfect for me.... The latest fight

He's 31 and has A suspended license plates are expired and just spent $160 and a flashlight and then gets mad at me when I ask him when is he getting his plates and his license back and look at my face to I'm not happy and that I don't wanna be with him... Which he states that what 26 year old lives at home with her parents... (A 26 year that sucking her pride and move back home because she had an abusive boyfriend and that needed to get back on her feet) 

So then he processed to tell me that I'm cut thought because I did my so called best friend dirty when he was the one that used me and then treated me like dirt and I stuck up for myself....

My best friend in ny and one in Japan have been a big support but I want other thoughts on this
