<human>: I'm at University and my GF stayed home to go to Community college and work, we've been together for almost 2 years. 

And basically she is depressed when I'm not around and was always really attached... and now she became good friends with her 21M boss at work (Walgreens) and said that he was a good friend and someone to talk and cared, and that she developed some feelings for home over a month or 2 and that she needed to see where the feelings go but she still loves me and I love her and that we have a legitimate chance of being together in the future.

 My fear is, is that this guy is using her...a 21 year old sees a new cashier come in that's cute and depressed, cozies  up, plays the friend game, jumps on an opportunity and then breaks her heart when she wants to be serious, I can't imagine this dick head just wants to take a serious relationship and make it another, I know guys do this all the time. 

And I don't know whether I should continue to contact her and talk to her everyday (which I'm doing right now) , cut contact and let her figure it out(honestly don't know if I could do that) , or warn her about what he may be doing (which she probably won't believe and will get angry). I love her more than anything and the last thing I want is for her to be heartbroken or hurt even though I am right now.

Could you distill the essence of the text into 1-3 sentences?
