Can anyone give me one good reason why I should trust this person?

He is a married man who flirted endlessly with me, told me he was married to his soul mate but she refused to work and they were in a financial mess and he was working all hrs day and night to try and stay afloat he also said his wife cheated on him with his best friend and he had to fight to keep her. I took pity n him and remained friends and conversed with him.Then out of the blue his friend told me he was planning on moving to saudi arabia lock stock and barrel taking his wife with him. I text him to wish him luck and ask him if he could p a message onto his friend about some money I owed him. I got a text back saying this is his wife and she wanted to know how I knew her husband. I freaked out and never responded the next morning when I logged into my facebook he had removed me as a friend so I text and asked him why. He said it wasn't him that had removed me and that I had put him in an awkward position with his wife texting him and wishing him luck because she had taken the day off work to go and see him perform and received his text on his phone (bare in mind he gave me his number and bombarded me with texts and emails daily). It has left my mind boggled because I told him I do not tolerate lies and he started attacking me verbally dragging my family into arguments and asking if I was on drugs for accusing him of lying. He also told me there wasn't one thing he had lied to me about and I had to stop blaming everyone else for my own problems and that I was needy, insecure and that if it was easier to blame him than realize I have problems then he pity's the next gullible poor sod that tries to get to know me. What would you do?
