I wish the last girl I was interested in had been as thoughtful about turning me down as you are now Evo!
I made it blatantly obvious that I was interested in this girl (which is hard for me since I tend to be shy about things like this). In short, she wasn't interested. She doesn't like trans-fat, so dating a box of fries was probably out of the question.
Instead of being open and up front about not wanting to date me, she avoided talking to me, made bad excuses as to why she couldn't meet me for lunch, and it became so awkward that I dreaded the thought of running into her on campus.
We were friends before all of this, but that is not so anymore. Of course, we are probably both to blame for the way things turned out. But still, if you want to remain friends with this man, my advice is to be open about your feelings. Don't avoid him or push him away because you don't want to deal with the issue. Otherwise you may end up in a situation similar to my own.
I would say invite him over. It would be best to have someone else there as well. Invite the child or spawn if necessary. Also, make sure he knows ahead of time that it won't be just him and you. He may then get the hint. If this doesn't work and he makes his interest more obvious when he is at your place, then you should be blatant and concrete about the fact that you are not interested in dating, but want to remain friends. Tell him so in words.
He may take this just fine and you may end up being friends. Or you may not stay friends because he's not interested in being just friends. Either way, at least now it is out of your hands. You made it blatant and concrete about your plans for the relationship between the two of you. You were open and did not hide or try to avoid the issue. I don't know what "Gumbo Man" is thinking, but I would respect this approach much more than a woman avoiding me because she didn't want to deal with the fact that I liked her. I would feel crappy for a little bit, but get over it and be content to be her friend.
Anyway, this is my opinion. It may not be a good approach I don't know. I just know that I would like if some of my previous unsuccessful interests had been more open and forward with how they felt about me.
