<human>: Can you succinctly summarize the text in 1-3 sentences?

Let's call her X. X and I have been dating for about one and a half years now, but recently we've had some trouble. X and I got into a fight about a month ago and ended up breaking up. The fight was about just a bunch of little things and it escalated to the break up. I cut off all contact with her, but a week after the break up she begged me to get back with her. 

I ended up giving her another chance, and for the past two weeks things have been great; however, she just dropped a huge bombshell on me. In the week that we weren't together she decided to have sex with two guys. I don't know if I'm overreacting or what but 

I am so fucking mad. What should I do? Does it make it ok that she fucked them because we weren't dating at that time? Please help me.
<bot>: Dated for 1.5 years, broke up for a week. Got back together after week, but during week she fucked other guys. What to do?
