I have been dating my boyfriend for 3 years now but it transpires that he has been double dating me with another woman since November 2008. He told her that he was single and has seen her whilst continuing our relationships as if nothing had happened, buying me presents, valentines cards, flowers etc.
I think that the other woman should know that he is a cheat and a liar and I have hundreds of texts on my phone that are explicit and would incrimnate him entirely - I dont want her to get hurt, and neither do I want him to be able to get away with it. She should be able to know the truth and then decide. He still wants us to be friends for golf etc and to carry on texting and calling me. He hasnt said so, but clearly is not keen on me telling her although he says that she will be fine with it and will continue their relationship. I dont want to hurt him though by possibly spoiling his relationship with her as she has kids.
What do you think I should do??
