<human>: Condense the text into a few key points

My girlfriend and I have been together for about 10 months and live together. I just found out the other day that she has been texting some guy from her new job. Looking through the texts it appears to me that she had no intentions of cheating on me but was very fond of the attention. This of course created a huge fight in which I almost threw her out. She showed her remorse and made me come to believe that she was no longer going to talk to him and would never again do something like this.

We were working on getting past that when I saw on her phone that throughout the duration of our relationship that she had also been texting some other guy from her college that she went to the year prior. The text messages included her saying things I wouldn't have said to another girl. Nothing inappropriate but still very wrong. Again I don't think cheating took place but these text messages were absolutely a stab in the heart.

After finding those additional texts I have thrown her out and she is now at her mother's house. This all just happened now and I guess I don't know how to progress. She is very clearly destroyed by all of this and has been begging me to let her come home. I see how hurt she is by what she has done to me but I don't know if that is enough for me to take her back.

So my real question here is "Is it worth throwing this relationship out over the things I've found?" She has admitted how wrong it was and that she didn't realize how toxic some of the stuff she was saying was. So should I move on? Should I give her a chance to prove that she'll never do it again? Do I give her a chance to fix things? What do I do?

I appreciate any feedback.
<bot>: My girlfriend has been texting other guys behind my back. She hasn't cheated but should these signals be enough even though she shows clear remorse.
