How do I trust in us and stop being possessive?
I have been 'friends' with a guy for over a year now. He asked me out about 10 months ago, but the idea of getting close to someone was something I really found daunting at the time and I said no. I had changed my mind a couple of days later, but he told me that he thought that my original answer was best, and that we should stay friends. And we did for a few months, but then I realised that I wanted more, and everyone thought that we were a couple. We spent most evenings together, and worked together so spent the days together as well. I asked him out again and he came up with some silly reasons we couldn't. Shortly afterward we started fooling around, and that was okay, but then I got ideas that we should be together again and he still didn't want to so we decided to stop that. But he still hugged me and gave me little kisses on the cheek and neck, telling me that I meant the world to him and he loved me. I had to leave where we worked but not before a new member of the friendship group told me that she liked him and that they had been emailing lots. I asked him if he was interested in her, he said 'only in the sense of having easy, meaningless sex'. He has told me that whilst he thinks that I am perfect for him, there is something missing, that he wants to go out there and have lots of 'experiences' and thinks he would resent settling down with me. But the idea of him with this girl kills me inside, I cannot sleep or eat. Add to that the fact that every time he goes out with the 'group' I hate it. I hate the fact that he might like them more then the old group, and might fall for this girl, even though I know deep deep down that he won't, the slight chance that he might really hurts and consumes me.
What do I do? How do I handle this?
Please help, any advice would be greatly appreciated!
