<human>: I'm only two years into my twenties, but relationships during this time of my life have been pretty awful so far. They all have a clear pattern and I'm kind of losing hope that it will ever change. 

I'll meet a guy (through friends, etc.), he'll get my number and show a lot of initial interest.  He asks me to hangout and over time we start hanging out often.  I'm into it and everything is awesome (cue the Lego Movie Everything is Awesome song).  Mutual feelings develop and are verbalized.  But as soon as it gets to the point where we may be headed towards some semblance of monogamy he'll start acting weird - taking forever to text me back, being too busy to hangout, and standoffish.  I'll ask him if we're okay (aka: if you want this to end just. tell. me.), he insists everything's fine, no he doesn't want to stop seeing me, etc.  Weirdness continues and whatever-the-fuck-thing we had going on ends as a result of his continued pulling away and my refusal to being treated like shit. Then after the whatever-the-fuck-thing dies I feel like shit about myself, emotionally raw, and confused as to what even happened.  

This pattern has varying time spans (shortest 3 weeks, longest 4 months) and happens with very different guys in their early twenties as well. My friend said I was sleeping with them "too soon" but they all end the same, regardless if we've had sex too soon or even at all.  I can't talk to my close friends about this because they all have similar experiences and we just end up bitching the issue to death.

Could you distill the essence of the text into 1-3 sentences?
