<human>: Hi guys, really need your help and opinion. 

So I've been dating this girl for 2 years (1 year in school and just over a year after college), and I do really like her. After all this time we've gotten to know each other a lot and our relationship is good (at least in my point of view). But sometimes, I feel like I want more than just good, I really want her to inspire me to make myself better. My friends tell me that if I'm not 100% head over heels about this girl after 2 years, then maybe it's time to move on. If I do move on, I have no idea how to tell her how I feel without absolutely destroying her self esteem. I really don't know what to do because if I keep staying in the relationship, it will be good and I'll have fun, but I don't know how much more I will grow. But on the other hand I don't want to hurt her...I will need to give her space if that happens, but I would still want to be her friend

Give me the gist of the text in a nutshell
<bot>: Relationship with a girl for 2 years. Everything is good with her, but I want more and feel inspired by her. Do I keep riding out the relationship or do I end it?
