Sorry guys this is long but PLEASE help me out!

I met a guy a month and a half ago at a friends party. We really liked each other and spent the whole time hanging out talking and before he left he gave me his number and we kissed a number of times. He didn't meet me for the next week but we exchanged a lot of text messages. At the end of the week he went to visit his family for two weeks.

We have a mutual friend who continuously kept messaging me and I liked talking to him, one day after work we met for drinks and after getting slightly tipsy he told me he really liked me and his friend had backed away because of him. This upset me, firstly because I had no idea why this guy would assume I liked him and secondly because it explained why the guy I liked didn't respond to my text after he returned, he sent me one text saying he thought it would not be right to talk as his friend liked me from before and he realized he was only in the middle once he got back from his trip.

I made it clear to his friend I was not interested and stopped txting both of them. After nearly a month the guy I liked txted me and asked what I felt for him. I was shocked and honestly speaking I still like him but I just wrote why he was asking to which he did not reply.

I tried calling him twice but his phone is either off or he doesn't answer. I just txted him and said if he is done playing I would like to talk, to which he replied and apologised for disappearing but explained that work had been hectic. He asked is I was OK calling him but when I did I got no response, is it because it's the weekend and he got busy or is he just being really weird?

Im sorry but I am so confused I have no idea what's going on in his head and I don't want to keep calling him. Does he like me?

Wait and see, as actions speak a whole lot louder than words. Don't call him, let him call you.

Ya I know that's what I need to do but I keep thinking that he might wonder why I ever met his friend..

I think he is a jerk, mature guys don't play games like that, so forget about him, time for you to focus on yourself and find someone else.

It wouldn't hurt to wait but I agree with Imnotok, there are some girls that message me and when I disregard them it simply means I'm not interested. If there is a girl I genuinely like, no matter what I'm doing I will get around to replying within a reasonable time limit.
Only reason I see someone ignoring a text is if he's asleep and he see's it and forgets about it the next day.
It's your call really it wouldn't hurt to wait, but this could be a hint of what games may come in the future. If you're comfortable with tolerating that sort of thing then the ball is in your court.
