Alright so, I'm going out with this guy. We used to have long convos with each other.. on myspace.. on aim.. in person. After a while, we would be really quiet around each other in person, but we would be able to talk fine on aim or myspace. So we decided to go somewhere together, just the two of us. We were able to go through the day with only a few awkward silences. We talked fine and everything.
For the rest of the week, I began to realize that our convos on Aim were dying. We no longer talked the way we used to. Our convos kept pausing for long periods of time.. and sometimes it just stopped and we wouldnt talk to each other at all.
My problem used to be the fact that we wouldnt be able to talk in person that well, and now it's like; we would talk fine in person, but we would barely talk on Aim.
Recently, he sorta canceled plans on me. We were supposed to go to a movie, but he decided not to go because he felt that if he wasnt going to be able to shower, he wouldnt go at all.
And now, I feel as if he's losing interest in me. I could tell from the way we dont even talk anymore. Also, he talks to one of my best friends alot. I'm starting to also get the feeling that he'd rather talk to her more than me, and thats just sorta.. lowering my self esteem? i dunno. it's not that i dont want him to not talk to her, it's just that its adding onto the feeling that he's losing interest in me.
So what do you suggest that I do? Should I just sit here and wait to see if anything changes? Or should I try to talk to him? Recently, people have been telling me to talk to him, but I'm kind of confused about what I should say to him.

You should really talk to him about it and tell him how you feel. Haha, sorry I'm a bad advice giver. Usually I'm the one looking for advice.
