move on?

Angelique

I wrote a post yesterday about my ex that cheated on me. well, his best friend texted me saying that my ex said that I can ask questions directly to him, but I don't want to start the text because his gf replies to me. Right now he is on and Im not sure if I ask him questions about why he decided to choose someone he already knew and not be adventurous with so e different like me. I am gf material and I'm nice to others and his gf gets on my nerves and I left a bad impression. should I let him go and move on?
