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

I haven't done anything that even remotely resembles emotional or physical cheating. However, I was on Facebook today and I saw pictures of my ex with other girls and I just got so sad.

Every now and then my ex calls, and we talk because we had an amicable break up and I still care about him. 

My current boyfriend knows that I'm still in contact with my ex, but doesn't know that I still have feelings for him. 

Is this okay? Is this normal? Should I not date anyone else till I'm completely over my ex? Will these feelings gradually fade as I start to fall for my current boyfriend more and more?
<bot>: I'm dating a new guy, I still have feelings for my ex. Should I break up with him until I'm over my ex, or is it okay to keep seeing him?
