Can my fiance get anywhere with this in court or by suing me?

So I just left my bipolar, alcoholic MANIAC fiance. I am 7 months pregnant, and one day he decided to drink all week and totally flipped. He has accused me of trying to kill him, killing my baby, stealing his money, having sex with neighbors in our bed, every possible thing you can imagine. His paranoia is off the charts. When I left, he hadn't eaten or slept for days and was drinking like a fish every night, but we parted on semi-good terms. I came back to the house after a week or so of little to no contact (the contact we did have he made it clear I wasn't welcome in my own home to stay away. Keep in mind, I'm pregnant with this man's child)! and the police made him leave so I could stay there. Both our names are on the lease. I went in the house (mainly wanted to stay there because I was trying to make an apt with my doctor in the state with my insurance, I've been staying with my parents out of state) and it was trashed, holes in the wall, writing on the wall in baby room, condoms everywhere and the handwriting of a woman on the calendar marking days 'Lexi came for a visist'. I was devastated he would do this in and to our home, I threw up maybe six times. :( So I took everything I could fit into my truck and drove home that night. Now he is claiming I robbed him (granted, he did pay for several of the things I took, but he had strange women all over our house doing god knows what while I'm gone for a WEEK and PREGNANT???). He's threatening to sue, etc, etc, but I'm under the understanding that in Arkansas if both inhabitants names are on the lease then whoever can take whatever? Would just like some info on whether or not he can get anywhere for me taking some of his electronics....I know for a fact he doesn't have any of the receipts for them. And the police made HIM leave. Btw, I am now out of the state completely and won't be going back.
