You can't afford the luxury of losing focus and forgetting how nasty and potentially violent this man is Zedsdead.Spending all that money on himself when his wife and kids are struggling isn't someone worth having in your life.
Keep the car and make him go back on his own steam.Finish with him and go no contact is my advice.

My sister got cut out my life two years ago.I didn't speak to her or see her all that time.But last June I found out she kept my spare keys and had been letting herself into my home while I was out having meals with my niece.She moved stuff and brought stuff from mum's house that was mine to my place.You can imagine the shocke confusion and doubt when I found things in my house that I knew had been elsewhere.She also bought back small swimming costumes I had given her to take to charity.I swore and cursed and fretted and was in shock.I changed the locks.

End of last year mum got cancer and the narc sister used it as a reason to get me exchanging texts with her,she wanted to pump me for information on how to cure cancer via diet and to find out where I got my CBD from.
I ended that when I understood I was being used.
Then last week I suspected narc sis had let her self in again,cos I found old toothbrushes that didn't belong to me and other **** in my bathroom cabinet.I had gone out and left the internal patio door lock unlocked so she let herself in the back.
So actually I had cut her out of my life but she is punishing me for it and making it hard cos she still hates me and wants me dead.
I have nothing but hatred for her and want no more to do with her.I am getting CCTV.I understand now how she has no empathy,no feelings,no care for me whatsoever,it is all about her,getting her needs met and getting what she wants.I have no feelings or trust left for her at all and the person I did love wasn't real it was all fake love,pretence,and I guess she fooled me.
