Search Results: picking up girls at the gym

I've started dating this guy I met online.
We've only been "talking" and "dating" for a month.
He texts a lot... that's it. He texts me EVERYDAY...
I voiced my concern that I would like to talk on the phone a little and he does only when I initiate it.
I initiate hanging out as well. I also voiced my concern to him that I feel like he doesn't like me like he says he does. He says he doesn't know why: he texts me, he meets up with me and he says he wants to see me again... I asked him why he likes me.. he said I'm different ( cliche ) and that I'm not a whore ( like other girls he met online?) and that I'm peculiar like him. That I'm a good influence as well because I don't smoke. He said his room mate used to smoke but his roommate turned into going to the gym and grew out of that phase. He told his roommate about me and he said his roommate approves that I don't smoke...
Like our dates.. I don't mine picking up the bill at all or paying for my meals.
First date we split it... Second date we split the bill... Third date, he paid but he says to pay him back or buy him stuff the next time. I don't know if I'm overthinking it.
I REALLY feel like he's still looking for something better to come along and that I'm not his type but because I approached him first on the website he will tolerate me...
We have kissed, we have held hands, we've hugged, we've touched each other sensually but have NOT had sex yet. I refuse to have it until I know him a little bit more. He says he won't make do anything im not comfortable with but when I'm with him he tries to push it thinking i'll give it up...
I like him for his personality.. I think it's cute and weird. His lifestyle SUCKS and he goes with the flow.. I'm not sure if I should just leave before I get dumped by him when he finds something better.
Do you think it's my insecurities or do I have a reason to worry?
