I pretended to a one night stand that I was pregnant to get abortion money?

I had twice with a man who I met at a nightclub. He resqued me from a gang of violent men and then bought me something to eat before taking me home. We had unprotected (he wanted to do it with a condom but I wouldn't let him). He invited me to see him again but this time we went to the cinema and he didn't want us to go back to his place.The third time I really liked him and we had again,this time protected. However after that he ****** me off saying I was a lier and annoying (which I am). I found out a few days ago I'm not pregnant but called him up to tell him that I was and the NHS couldn't give me an abortion until two weeks and that in my conscience I couldn't abort that late. He agreed to pay the 350 pounds if I paid 100. I met up with him and took the money in cash. Now however a few days later I realise how sweet a guy he actually is and am wwracked with guilt. Even if he was a prick he wouldn't deserve that. I feel really guilty. Should I tell him the truth?
