I work at a charity org. So I travel a lot, go to a lot of parties, and yeah, meet some interesting guys/wealthy donors. That wasn't a problem for about three month. He loved how friendly I was and I was always put together nice; around three months later my boyfriend started getting more insecure. He's been on trips with me; he knows the people I travel with. I try to keep in touch as much as possible. But in spite of that he still is convinced I'm going to leave him for some guy that I meet at these events. He says he knows I won't cheat on him; but he still feels this way. I don't know how to help?
