<human>: It's been unofficially three months of dating a [28/M] and before this I was blissfully happy [24/F]. Until I find that the guy I've been spending LOTS of time and sleeping with is on other dating sites and looking for hookups.  

I know it looks like a double standard and that I'm looking at dating sites, but in this case it was by accident, and I wish I could go back and make it unseen.  I know it's new and we have yet to have "the talk" but is it worth continuing when being with me is not enough? I'd like to think I'm of value and have some self worth.

I felt like this might have been someone I could be with for a long time and now I'm just not so sure. Clearly this is an open relationship to him and I'm unaware. I truly believe it would be easier to walk away if I didn't feel so ashamed. Now I feel like I want to make it work to in order myself feel better. Also, is it a good idea to confront him?

Summarize the given text in a few sentences.
<bot>: Girl finds new guy's dating profiles for one night stands; not sure if to continue to date or let him go/confront him.
