I messed up

I said something really dumb that could cost me my relationship. I have been with this girl for a little more than a year, and I give her my all, but she is off at college now and it makes my stress levels very high, especially when she talks about other guys. It’s not that I don’t trust her, just that I got jealous. Either way one night she was texting her mother about her new friend, happens to be a guy. She had talked about how nice he is and how he makes her feel smart because she can help him with his work. Of corse I got jealous. She accidentally sent me one of the texts intended for her mother and I freaked out. I told her I didn’t believe that she was texting her mother, and that I was so jealous. She called me and asked how long I have been thinking about this. I told he since she moved. And was so irritated with me and now she doesn’t know if she wants to stay with me or if she ways to break up. I’ve apologized many time and even talked to her. She just doesn’t know if she can trust me or not. What do I do, because if it wasn’t for this, we would be smooth sailing.

Sounds sus to me.

Why would she throw back the trust thing at you when she is the one you worry about not being able to trust, deflection to hide guilt?
You don't bang on to your mum about a guy unless you like that guy, and if you have a Bf you don't do that, so maybe she wanted to break up and she is using you getting jealous as an excuse so no blame falls on her?
Idk sit and talk about it calmly, she loves you, doesn't she?
