I have this friend that I know for about 3 years now. A couple months after we met, we started to call each others nicknames based on our inside jokes and stuff. One day, we ended up flirting and sexting and we did for a couple times. He always gives me serious signs of interest and then he can go distant for a couple days, so I don't bother him. He mentioned to me a couple times that he miss me and that he is happy to see me again, we have normal friends talks but always ends up in flirting. He mentioned that he got heartbroken in the past. Not sure if it would mean something, if he have feelings for me or just playing. I have no idea what is going on, what all this means. I feel anxious to ask or end up heartbroken.
