<human>: Can you give me a shortened version of the text?

I really care about her, she is extremely important to me and I want her to be happy, but I don't think I can be what she is looking for anymore. It's not about fights (it was at one point) or anything like that.

We started dating right after we graduated high school a couple years ago, which is a point in our lives when we change, and not necessarily in a bad way, but more in a way where I don't feel as compatible as we used to be. I just don't feel the same anymore.

Tonight, me and her went to have dinner after I got back from work. I picked her up and we were conversing a bit, but as soon as we got to the restaurant, I stopped talking, almost completely. I hardly made eye contact with her. It wasn't an awkward silence thing, but more of a "this feels wrong" thing. After we ate, she got up and went to the bathroom. When she got back I could tell she had been crying.

It really crushes my heart to see her like that, but I want to do the right thing. I know if I stay with her, it will be bad for me and her, but if I leave her, it will stick with her for a while. I know I don't have many choices here but I just want to hear what anyone else has to say. I need to make this right. I don't want to be a shitty boyfriend anymore, I just want her to be happy.
<bot>: I am having a hard time making my girlfriend happy because I am losing interest. I would love another point of view or some advice. I want her to be happy.
