New roommates

I got a random message for this guy (lets call him J) on and we sent
messages back and fourth, but really never talked about meeting or anything
like that. Well, I started to hang out with this other kid (lets call him
D), and I went to his apartment....

Turns out he has 3 other guy roommates. We
all sat around and talked and I kept looking at J cause he looked familiar.
Well when I got home, I got on here and check my messages. J sent me a
message while I was sitting in front of him. He didn't notice that I was
the same girl that he was looking at on the computer. I let him know that I
was the girl that was over with D.

When I was over there D started to fall for me quick and stuff happen, and
I felt really bad about it. Well we only dated for like less then a week.
We broke up cause he thought I had a thing for J. D kept bad talkin bout me
to J, and of course J told me, cause he is a good friend.

Well now that D and I broke up (after a whole freakin week!) is it wrong
for me to still go over to the apartment to chill with J? and is it bad
that the more I start talkin to J, the more I might start actually like
him?

They will be living with each other for two years in the dorm apartments I
don't wanna cause drama.

why not get him to chill with you somewhere else? It could be taken as wrong by some people but im sure the same people who think its wrong would do it.
