Feeling hurt and let down?

I am engaged and getting married to my partner at the end of this year. I recently went through a very difficult period a few months ago and a person who I thought could be trusted befriended me and persuaded me to confide in him. He is an Iranian multi - millionaire and I guess he thought he could do whatever he wanted as he came onto me when I was at my most vulnerable. I refused his advances and I have now seen him for what he is. He seemed to care but he was completely false. Now that I have rejected him, he isn't interested in our 'friendship' anymore. I shouldn't be surprised really. I should have seen it coming but I really wanted to believe that he was genuine. Silly me eh? I guess this is the sorry world we live in nowadays. I did the right thing at least. I told my partner what happened and he is really angry with this guy (not surprisingly). Just needed to vent. Need cheering up - feeling a bit low. Thanks for listening.
