He says he doesn’t feel the same way

I have been trying to go out with a guy I know for a few months now but, whenever we make plans and meet for dinner or something, he goes out of his way to mention that this is just a casual meeting. He obviously knows I like him because I don’t hide my feelings, but I don’t understand why he meets me if he doesn’t feel the same way. If we aren’t dating, and he isn’t interested in a relationship, why go through all the trouble of meeting me and then mentioning that this is nothing special? Is he playing some kind of twisted game, and should I call him out on it? Alternatively, should I just stop trying to meet him if he is just wasting my time?

Why not come right out and ask him? There is nothing wrong with him not reciprocating your feelings. Why not consider the possibility that he has no romantic feelings for you but genuinely likes spending time with you anyway? Isn’t that what friendship is about? If he wants to be your friend, would you reject that option simply because he doesn’t have feelings for you? The easier way to figure this out is to be open about what your expectations are and give him a chance to be as transparent. There’s no point trying to second guess everything, especially because you have nothing to lose by just asking him.
What can I do to make my relationship with my girlfriend stronger? We have been together for eight months, but it still feels shallow for some reason. We meet, go on dates, talk about our personal and professional lives, but it doesn’t feel like something solid, and I can’t explain why.
A good thing to do is put this question to her and find out if she feels the same way. If it feels solid enough for her, maybe you should both talk about your individual definitions of what a healthy and meaningful relationship is meant to be like.
