My friend is like that. He is not on the rebound or anything, but he acts hot then cold. We hang out, we share Bible study notes, we occasionally worship together at church, we mildly flirt, but he just doesn't seem to want to be in a relationship with me because I'm not (physically) his "type". Sorry, but I'm not the 6' tall rail thin brunette modelesque type. Now if he could get over his shallow desires to have the "perfect woman" then there would be a possibility. He's definitely the type of man I could honor and serve in every capacity and we've been close friends for years and years. We know alot about one another. We've seen each other in all aspects of life from family interaction, in group settings, in casual settings, work (since we used to be co-workers for two years), church, Bible study, ministry work, etc. But, he won't let go of his fleshly desire to have the ideal woman and knowing him the way I do he probably won't ever get that kind of girl. Yes, he's attractive; however, he isn't the type of guy girls like that go for. He isn't rich, he has a kid, he isn't Mr. Personality. I don't know, in this case I think he just needs to lower his standards of ideal physical appearance just a tad. Even when we were working together and I was thinner than I am now, he was adamant that I wasn't his type. So adamant, in fact, that one night he and I went dancing and he told me the entire drive to the club "You know we're just going as friends, right? If we dance, I'm not touching you...okay?" I don't know if that was just a way of maintaining purity in a rather sexual setting (we don't do the "clubbing" scene anymore) or if he was trying to let me know under no uncertain terms was he going to allow me to be confused thinking he was attracted to me. He and I also used to do alot of DJ'ing together. He taught me how to spin and mix trance and breaks and we used to hang out at his friend's place and do that until 3am some nights.
Anyway, I swear I have a point to all of this. I think sometimes men in our lives who really treasure our friendship and feel some level of attraction towards us get spooked. Women tend to think romantically whereas men think rationally. They starting thinking about ruining the friendship and things like that. They're scared to take the plunge. But they always come running back to us, the gal pals, when another one of their relationships fall apart. Maybe, in a sense, we are the rebound girls anyway.
