<human>: Summarize the given text in a few sentences.

Ok so basically I still love her and we have been through basically everything together. We are long distance and made it work through the first year of college and everything was great. 

But as the year ended and summer was starting we started to fight a lot more and things just kept going downhill. She was like forcing us to spend all our time together. And I really messed up and lost some trust by texting a friend that I thought another girl was hot. But she violated my trust by going through my phone and snooping on it. 

Now nothing really feels the same anymore unless we are doing something fun. Like we went on an awesome vacation with my family. 

I thought we would be together forever but it feels different like we are reaching an expiration date. With that in mind what should I do? And how should I do it? I've never broken up with somebody and I am terrified that I will not find another girl like her.
<bot>: I think I need to break up with HS sweetheart but don't know how and don't have the courage to.
