in short

I have been dating this girl for 4 1/2 yrs but things are not working out and I think we are going to end it soon. I dont want it to after 4 1/2 yrs but no matter what I do it is not good enough. She is about to finish teachers college and I saw her through University and now this. But I'm to the point where I want something more and she wants something but the communication is just not there. I do everything for our relationship, clean, take care of our cats, the car, work full time and now looking for a second job to pay all our bills. I tell her all the time how much I love here and that she is sexy all the time, even first thing in the morning or when she is sick. I have read so many blogs and I have visited so many website to learn more about how to communicate and make relationships work better. I’m out of idea’s and need some advice, I really want to save my relationship but to tell you all the truth I think it is too late.
