<human>: Give me the gist of the text in a nutshell

We met through a mutual friend. He sent me a friend request on Facebook. He asked me out for a beer, we had a good time. He messages me every now and then, compliments my looks and hints at finding me attractive. I didn't pick up this as I am not interested in him romantically. 

As for suspicious behavior, he often ends the conversation abruptly only to start it all over again two or three days later. He suggests we meet and then uses work as an excuse. He sometimes insisted that we meet at my place, but eventually he never had the time to visit me... which, I think, is a good thing because of what I just discovered: I saw a profile of a girl in friend suggestions on FB, visited the profile, and it turns out she is "in a relationship" with the guy in question.

I don't know what to think about this guy as he never mentioned any girlfriend, I've also never been to his place. I am obviously not interested in dating him... or even meeting for a beer anymore. And I used to think that he is just busy etc.

I think I know what's going on but I am curious if any of you encounter similar situation? Were your suspicions later confirmed?
<bot>: An acquaintance seems to be interested in me, wants to meet, preferably at my place, but almost never has the time. It also turns out that he has a secret girlfriend.
