I am going into the Air Force in about 6 months. My boyfriend and I have been talking about staying together and when I get back getting married or even him coming with me. But the other day he started saying he has been fantasizing that I meet people while I'm away and have sex with them. I told him I wasn't interested in having sex with other people while away. I love him and only him. I asked if he wanted to have sex with other people while I'm away and he said that he may want to cause I'll be gone. I don't know what to do or how to talk to him about this. Please help.
