<human>: Can you give me the gist of the text in a nutshell?

I don't know how to feel.

We started as friend with benefits because he was about to move across the country in a few months, so we stayed casual (obviously it ended up working out later). 

When we were fwb we agreed to be very honest with each other. In the beginning he had sex with another person one time and as did I, and we both told each right away when each happened, used condoms, etc. Back then, he lied and made it clear it was only "one time".

I've just found for the first two to three months of our relationship he was not only having sex with another girl in a different city but also having a full fledged emotional relationship, texting her everyday just like he was me, etc. He later completely broke it off and "chose" me (we started dating seriously shortly after).

I'm not sure if I should be mad? I am mildly disgusted that the wool was pulled over my eyes. I thought we were being honest with each other back then.. However ever since our commitment to each other things have been very amazing and wonderful. We get along amazingly and I trust him completely.

I'm not sure. If you were in my position, how would you feel? Let the past be the past, or feel scorned..?
<bot>: boyfriend had two girls on a string at the same time and didn't tell either.. But never really "cheated". Not sure if I have any right to be angry or I should just let it go
