I understand your pain for sure. I did the live-in girlfriend myself for a year and a half, and when the break up happened, there was quite a lot of drama and such. For a few days, we had "our side of the bed", then I just basically relegated myself to the couch permanently (still haven't moved back, lol, it's comfy).
That was months ago, and it feels nice to be rid of the whole thing. You deserve better, most certainly. There are some things that people just have to have in common or it just won't work out in the long run. I am a major commitment person myself, and lately all I have been finding are people who are new to the commitment thing or are completely opposed to the idea (it's strange being a guy and having ladies wanting the relationship to be "friends with benefits").
I think it is all a matter of just living your life, not secluding yourself, and eventually the right thing will come along. Putting yourself out there a bit helps. Desperation shouldn't be part of your game plan, as that only gets you the worst kind of people.
But what do I know? I am one of those dumb boys after all.
ROFL, as a side note, all of my friends (at least 7, 8 counting me) are males between the ages of 22-25, are all gamers and into anime, and are all single. I already got 3 of them to agree to come to the con.
I should stop lurking and become more official on here..
