He cheated on someone else with me and I had no clue

Madeline • 20 Mom to a beautiful baby girl

Okay, so I met this guy and we really hit it off. I thought we really liked each other and we have been talking for a little while. He snap chatted me today saying that he has had a girl for over a year now (we have only been talking a couple of months, we weren’t in love and aren’t in love) I didn’t know what to say, I’m really glad he told me but I hate being used and I don’t know what to do. I had no clue he was dating someone else until he told me. I feel humiliated. I’ve not been with someone in over a year and this is the first guy I talked to in this way and it’s so annoying that this is what happened. Any advice?
