I am in need of sisterly support who ever can offer it

Rogue
Well my ex just texted me out of the blue and told me he is in a relationship with this girl who he cheated on me with when we were together. 
I was having a great day and now I feel sad and cold. 
Also question. If I am starting over with a new guy and he talks to me about everything and always asks what's wrong should I tell him about this?
This has my facial expression
