<human>: So my gf and I have been dating since freshman year of high school. We went to different schools and its worked out pretty well. The only problem is is how different we are--she is super smart and beautiful and wealthy and I'm just average.

We have a common group of friends that we all hang out with. Sometimes she hangs out with her other friends from her team and won't text me back in that time. I tell her that it's not htat hard to send a text and that she needs to text me back.

Because of her sport shes also around guys a lot. Now she's super gorgeous and everyone knows it so obviously it worries me. I'm worried that someone is going to steal her away from me. I tell her about this all the time.

Also, my family is kind of a pain. My dad said early on that she was using me because I would always drive to her house when we would hang out, even though she couldn't drive. My family hasn't been really accepting of her.

She has this event for her sport every year and one year my family was having a night together and she got really upset that I wasn't coming.

She's really smart so she got a really good offer to a school out of state. I told her that I didn't want her to go and that there's good schools here but she's going anyway. I'm really upset about this and I'm nervous shes' going to cheat on me there.

Can you summarize the given text in a few sentences?
<bot>: Should I be worried about my gf cheating/do you think she's cheated already? How can I keep her from cheating?
