<human>: About a week after we broke up she slept with another guy. We started talking about a week after that happened and now are starting to get back together but I don't think I should take her back because I see her act as an act of betrayal even though we were broken up. 

I see her as a whore and I think its wrong that I do. She had every right to do what she wishes, we were not longer dating. I know she only did it to try to get over me but im just not sure what I should think.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My (ex)girlfriend I are broke up, she slept with another guy, now we are trying to get back together and I am not sure if I should take her back.
