I need your advice

It was quite weird to be honest right here goes. Mark moved out of our place around 3 weeks ago and into the spare room of a guy that is in his group of friends at work, up to him moving out like I had said before he had shown no emotion really what so ever and when he did move out he was a wreck, I last saw him 3 weeks ago and he met up with me yesterday and asked to meet up with me, so he walked in and went to hug me and we also kissed and it was obvious that he had missed me you could tell so we were having a chat about my holiday and I asked him how his love life was and he said that he needed to chat to me about it so I was like ok tell me and he sat down and you could tell he was nervous and getting upset and he basically told me that he has done stuff with the guy that he's living with, only during the time since he's moved out and on 4 different occasions, so I asked him if it was full on sex and he was like no and I asked him how it started and mark was like we were sat on the sofa and I just went into kiss him and it went from there, so he was telling me and he was holding my hand and you could tell he was shaken up, so I asked him why he was telling me and he told me that he thought I had a right to know when really I don't as I'm single and so was he and I asked him when the last time it happened was and he said last weekend, as the lad had told him that he needed to make up his mind what mark wanted in his head, now he told me that his mates at work had said to him that him and this lad would make a good couple now I think that this has fucked with his head a bit and I also get the feeling he is lonely, this lad by the way is older then me and fucking gross, I've asked if any of his mates know about it and he said yes and that they are telling him he needs to think about what he wants, I asked him if he had feelings for this lad and he said no, I asked him what his options were, was it being single or getting with me or this lad and he was like being single or with you, also he told me it was a mistake and that he didn't want to talk about it anymore, and when I asked questions later in the day he started getting annoyed saying he wanted to stop thinking about it, he told me that he had been worked up so much about meeting me and really nervous about it but why? He keeps telling me how much that his mates have seen that he misses me and that its effected him. Yesterday we kissed a few times and it was so obvious that we missed each other but am I wrong for being slightly pissed off for him doing what he's done or should I not be as technically he didn't have any reason to tell me he could of lied x

He's got the gist that you fancy him and is playing up to that. Yet the minute you start to press him for details and a more spelled-out, more committed frame of mind and plan of action in regards to you/not the other guy or anyone else, he, Mr Motor-Mouth, suddenly clams up under the excuse of not wanting to talk about it any more. "Er - pardon? SINCE WHEN?!" I get the feeling that this guy has, unbeknownst to you, only recently found his sexual feet and is enjoying the novelty of collecting admirers (who become such out of a belief he's interested in them first with more than just a little help from him, quite possibly using this one same method) or, perhaps truer to say, admiring eyes. Because he's not picking anybody, he's flitting in terms of his attention. Note how it's allegedly not HE who's recognised that he misses you, but his friends. This is a commitmentphobe-style statement which places any future blame (in the likely eventuality of his suddenly pulling out of what seemed to you by then to be a flourishing relationship) onto them. Think about it: he could have just said, 'I miss you and it's affecting me' berbom. No, you're NOT wrong. Plus, you did in fact make it crystal clear that you feel as much for him as he alleges to feel for you - via your list of what you believed his options were. So why didn't he grab that golden opportunity there and then to make a move? Interesting question, huh?.....aaaand we're back to 'admiring eyes' because you're left with a loose end you feel could still be tied to his...and that's the way it'll stay, I reckon.
