Your question was: Mixed Signals.
He is not interested. Sorry to break it to you, but if he was, he would be the one asking you out. You wouldn't be sitting wondering if he liked you or not, because it would be obvious. Boys and girls flirt all the time. Either sex can be huge flirts and that's all it is. It doesn't mean they want to date. You've asked him out so many times already! I would not have gone as far as you have. You've done enough. Time to move on to bigger and better things (or men)... ..
"Is it just conversation, or is he hinting at something else? "> just conversation.
I dont see a big drive in him wanting to be with you, calling you, asking you out. If you pulled back on the invitations would you continue to see him or would things just fade away? These are the things you need to ask yourself. ..
See, that's what I thought too! But I have this tendency to listen to my friends at work, because they know the situation and they are an outside observer. I really should just learn to listen to myself! Thanks!..
It does sound like he enjoys your company but there's ambivalence. You asked him out to dinner and he said no without offering an alternative plan. So next move if any is up to him. But certainly feel free to put energy toward trying to meet other people.
