Am I Missing Something?

I haven't blogged in quite a while but I've felt the need to vent about something lately. 

Am I missing something?  That's a question I've been asking myself a lot lately.  Where I'm live there isn't a deep pool of gay men.  It's more like a kiddie pool (shallow and gets peed in frequently).  The guys here seem to not want to, or maybe not have the capacity to, grow up. With that said, they want to be loved, we all do but is the way they go about it the right way?  Is there a right way?  It seems to me they've all dated each other and are on again off again friends, especially when they switch from one friend to the other.  How is it that they can go from 'loving' someone so deeply one week to being in love with someone different the next week.
I've witnessed a long term relationship end and two weeks later one of the men was already dating someone else and expressing their love on Facebook.  Maybe they were in love, who am I to say they weren't, but it took about a month (two at most) for this relationship to end as well.  A week or two later the guy is dating someone else already and talking about how happy they are on Facebook.  Again, maybe they are happy.  I'm not an expert on love, obviously, or I'd probably still be in one of my past relationships or even committing to one of the potential suitors I have now.
Maybe I'm too careful with my heart.  Maybe I don't trust easily.  Maybe I'm cynical.  I just can't fathom telling someone I'm in love with them within a week or two of being together.  Even if I've known the person as a friend before they became more.  I don't understand how people can flit from one relationship to the next and seemingly not be effected by it.  The people they were with sure seem to be effected.  Maybe this guy feels a need to be taken care of, who knows.  Maybe he's really in love with all of these men and falls out of love just as quickly.  I guess I'm not the one to answer these questions and I just continue to wonder, "Am I missing something?"
