I did a very stupid thing...

I have been talking to my ex boyfriend on a text message. The one that cheated on me. He apologized to me and he wants us to get back together. When he asked me to get back together, I didn’t answer. I starting crying because....I don’t know. Parts of me still likes him but I don’t know how he will act.
Of course I didn’t tell my best friends about it because I know they’re going to scold at me for talking to my ex boyfriend. My family would call me out too.
