<human>: My girlfriend of more than a year is a great person, but I'm not sure if I want to spend the rest of my life with her. I am attracted to her, physically, but not necessarily more than other women. In terms of personality, I realize that she is a good, caring and honest person, but sometimes she can be a bit annoying/intense/clingy.

Overall, she is kind, caring, willing to sacrifice, etc. but sometimes she gets on my nerves. I really care for her a lot, but It's not the same passionate love it used to be. Is that just inevitable for relationships, or is something wrong? She is a great person, but could I ever find somebody that makes me happier? Am I just an unhappy person, or could I be happier with somebody else, do you think?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I am not unhappy with my relationship, but it doesn't really excite me the way it used to. Is that normal and not worth making a change over, or in your experience is that a bigger issue?
