<human>: Last night after a heavy night of drinking for both of us a fight ensued. Neither of us recall why we were fighting, but my girlfriend thought I was going to break up with her. 

About two hours later I opened up her laptop and found that she had sent texts to a guy I had never heard of. They were along the lines of

"Hey I never respond to you because I have a boyfriend, but I'm pretty sure we are breaking up. How fucked up is that? I'm really drunk. I wish that when I text you it was something more than sex, do you want that?" 

I immediately confronted her and told her we were breaking up. I came to find out that she had hooked up with this guy on and off since freshman year of college. She swears she hasn't since we've been dating, and the fact that she said to him she was ignoring him I believe that.

She spent the night and we talked about it this morning. I told her we could try to work it out, and she apologized and told me she doesn't know what she sent them. My question is the relationship worth continuing? I asked her to delete his number and she immediately. We've been together for five months, we all do stupid shit drunk, and she sent them under the impression that we were broken up.

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