<human>: In every long-term relationship I've had (I know, i'm only young, but i've been a long-term relationship kind of guy since I was about 14), I've always found myself to be the "chaser" in my relationships.

Now, initially the girls seem to be just as much into me as I am to them. But as time goes by, I try my hardest to keep things as "lovey-dovey" as they were from the beginning, because I'd hate to be in a relationship where you never compliment each other or make each other smile. But as always, this girl who I fell "head-over-heels" (lack of a better term) for has slowly but surely lost interest in me.
Any advice as to how to move on without her? Keep in mind when I love I love fully, and kind of give away half of my heart to the girl, so it makes things VERY difficult when it ends, but it's the type of person that I am.

And to get back to the initial question, is it bad that i'm a "chaser", if so, what can I do about it?

Can you give me a shortened version of the text?
<bot>: I love fully and when we break-up it hurts so much. Any advice for moving on with my life? Should I be the "chaser" in my relationship?
