<human>: My girlfriend and I are both full time college and we live together. I have a full time job and she works part time. Everything has been great for the past 3 years up until recently when she made a new guy friend in one of her classes.

For the past week, she has been constantly texting him, from the moment she wakes up at 6 am up until 2 or 3 am at night, even when I fall asleep. When im at work, she texts me a couple times, but I got to read her messages and she is texting him every couple of minutes, when she could be texting me.

She has let me read the text messages and swears that its nothing and they are just friends. She also said that she feels lonely when I am gone and just needs someone to talk to and fill the void. Overall, the conversations they have are pretty school specific with a little bit of flirting both ways.

I have been direct with her and she cries and swears that its nothing and I have nothing to worry about. Is this just me being jealous and over reactive, or does this seem like the first sign that our relationship is falling apart?

I really have no idea what to do besides let time sort things out. I love her so much and she says she feels the same way but I have no idea how to tell based on her actions with this new friend.

Any advice is appreciated!

Can you condense the text into three sentences or less?
