Sorry, sounds rough. I wish I could relate, but I can't, because I have never been in any kind of relationship and I don't even know how to approach girls. I am 28 now and have gotten crushes on all sorts of different girls, but I have never been able to connect with any of them. It is most likely caused by some undiagnosed issue like a deficit in cognitive processing or perhaps some form of autism or both. Therapy has not helped and there seems to be nothing I can do about it. I just have to watch other guys get all the girls I like and get jealous and angry. And pretty soon most of the girls I would be interested in will be off limits because society will deem them too young. Basically life sucks and all people have to say about it is "quite whining".
Hope that makes you feel that least a bit better about the situation you're in.
