I'm sorry this relationship didn't work out, but it sounds like it wasn't meant to be. And I know he meant it, but I don't think the "now let us just be friends" will work out, if only because his new girl won't like it.
It sounds like you got too attached to him to the detriment of other relationships, so now that he is gone, you are currently without a support. So, I suggest you start looking around for a social life--even with some girl friends--such as going out to the movies, for lunch, or whatever. And, of course, keep your peepers open for a new guy.
In the meantime, although we can't take the place of people you can touch, we are here at Psych Central, with plenty of people for you to talk to and interact with.
