I sold my home and signed a lease with my boyfriend for 2 years. I paid the full amount for the rent up front(which I now see was a bad idea). This was so I could go to college fulltime and not worry about working knowing that the rent is paid while I get my degree.

My boyfriend and I had a verbal agreement, I paid the 2 years, bought all new furniture and appliances, and did some upgrades. He was to pay the essentials(electric, insurance, phone) and groceries. Soon into this was not happening. I depleted the money that I had paying what he should have. He was also to maintain the yard and his pet, which he has not.
He also had added onto the lease that he would replace the interior doors,(there are 6 he did one), redo kitchen floor, bathroom vanity and he has not.
Because of all this we have split up, we no longer sleep on the same floor and he will not leave(I guess I wouldnt either if I were a louse) He is verbally abusive to me and my children, but will not leave
What legal action can I take to have him removed from the lease. I have the money to do so, please tell me where to begin
