The other week when I saw him he acted kind of rude compared to the other times. The next day I casually asked pointed it out and asked him if everything was cool and he said "Yeah it's all good"Then a week later (which I was surprised to hear from him in a weeks time at this point) he said "Hey Sexy what are you doing tomorrow night?" So I saw him again. He was much better this time and we started talking about food/restauramts at one point and I was telling him about this cool Greek restaurant close by (he's half Greek). He said that sounded so cool. I'm in the middle of doing finals/exams in college and he told me to let him know when I'm finishing because he wants to go to the restaurant.
So I've never had a "hook up" type relationship last a year.. especially one thats been so consistent. and now next time we're suposedly going out to that restaurant. He's never pointed out he likes me or anything either, we never talked about our feelings. What should I do when I text him next? and why has he been sticking around for so long?
