<human>: Can you give me the gist of the text in a nutshell?

Have been seeing this guy for about 3 months. We were not officialy dating because we never had the talk about it between each other, but are practically like a couple just without the lable.

Lately, he's been hot and cold with me. Wanting to hangout everyday, texting me everyday, spending the night at his place to not hearing from him for days, getting breif texts whenever I try to initiate contact and not asking to see each other during the week. 

Last weekend, he went away out of town for work and I didn't hear from him at all and he claimed he forgot his phone but I heard from a mutual friend today that she spoke to him during that time.

It's just very frustrating for me as I don't want to keep investing my time and myself emotionally just to possibly get hurt or so in the end.

What should I do in this situation? Do nothing and leave him to make the move? Forget it all and just move on?
