My ex-boyfriend and I broke up about 8 months ago. About 4 months ago he called me because after 2 months of renting a room from somone, that landlord gave him a 30 day notice and put him out. So he asked me can he come stay here in my house. I told him yes but he can only stay for 90 days, 3 months & that will give him time to get himself together. He moved in my house in November and the agreement was that he would pay me $300 per month. First I asked $375 but he said he could not afford that right now, so I reduced it to $300 to help him out. He has not paid me any rent since he has been in the house because he wants us back together and I am not going back down that path with him. I asked him to leave but he told me that he will leave when he finds a place. I gave him a 30 day notice that I personally typed up and had notarized on Dec.31 and told him he had to leave by 1/31. He said he would but I don't believe it.
I checked with a police officer in Charlotte, NC and he said there is a freeloader law. Due to him not paying rent, paying any bills, contributing to any groceries or fixing anything in the house, I can put him out immediately.

Is this correct? Can I put him out immediately and ask the officer to arrest him when he leaves for driving without a license and having 2 warrants? Please help me, I have 2 kids, 16 & 4 and I am struggling maintaining the bills I have without having to put up with him too.

Thank you so much.
