MY TAKE ON YOUR PROBLEM:
I don't understand your problem! It sounds like you live a great life for a 25 year old. Seriously man there is no true happiness, think about what you are starting to search for. Eventually when you are in a long relationship you are gonna want to go back to being single because it is fun to have lots of different pink.
Quit being sad over nothing, the right girl will snatch you up soon enough, and then in two years you are gonna wanna be single again, cause you have had the same girl and now you want new stuff cause there is tons of hotass walking around. There is no good answer.
MY PROBLEM:
My problem is that every girl I have dated are really good girls and then I stay with them too long. I am only 23 and have been in a 10 month, 3 year, a few 3 months, and am currently in a just over 2 years relationship. I have been pretty much taken since I was [censored] 16. I am not saying I am unhappy but I would like for a girl to dump me once in a while. I mean I want to increase my # before I get married.

So again there is no good answer, just try and be happy with what you got, cause it sounds like you got it good!
