Cockroaches in my head...

For several years I have been communicating with a young man, we have never been a couple, and we have never aspired to this (and now I do not need it). We just spend time together in a common company. But the last time I do not always understand the cockroaches in his head ... Jealousy for a better friend, finding out the relationship is not existing (with nothing but drunk), no one needs the recognition. Not long ago celebrated together birthday was all good, had a good time, talked and then as a bag on the head "we can not be together" ... why are you telling me this, if I did not even give a hint, for what I want with you what Any relationship!?! I know this man too well and understand perfectly that NOT my person .... Ha, he also loves to ask for forgiveness (it would be better if he did not do it), while he says forgive me, but I could not fall in love with you ... Why are you telling me this! ??? !!! I after all do not demand it !!! Sometimes I'm crazy about madness from all this delirium, then without you I can not, then we can not be together. Well, why can not we just spend time ... That's how he is sober all the way he drinks, the cockroaches in his head go crazy, then he says he does not remember anything, but I remember that and try to truly understand all this ... Oh, and this one his jealousy (for the best friend married to my best friend), "you just love him, he is the best for you ..."

I do not know why I described all this nonsense, I do not know how to behave better and what it all means.
