Please guys i need your advice please help?

sorry for the length but please guys can anyone advise. ive known a guy for over a year. I thought we were good friends hes had a lot of personal issues and trauma which ive been there for him, hes borrowed a fairly large amount �400 ? in bits over the past year-when he gets aid never mentions it. ive bought him loads of stff-anything from ps3 games to dvds as presents-stupidly i admit i was very fond of him and now i see im a fool. what my real problem is i feel hes always been skant with the truth and comes out with wild elaborate tales always like hes got a car and a �60,000 share in a business and he always seems skint and i feel hes making a fool of me. without wanting return ive freely given him time and the other stuff so why would he repay me by lying ? the other day he was talking about his ex wifes mum who neede some building work and that he'd have to find a surveyor. i gave him a weird look and he said what ? and i said dont you own a share in a building firm ??? why cant they help and he looked sheepish. so i said 'what this companies name again ?' and he said i was distrusting of him and stormed off. im so fed up all ive tried to do is be a friend abut i feel like a right ***. what should i do guys ? sorry its so long :(
