person A: I wish I didn't cheat on my now ex-gf
person B: Hindsight and all that - do you miss her?
person A: Yes a lot.  I've accepted it but it's hard letting go
person B: Perhaps she may forgive you?  It's always worth a try_comma_ sometimes you just need some time and some growth before you can revisit mistakes that have happened.
person A: Thanks.
