Do you believe in second chances?

[_Cathy_]

It depends on the reason for break up.

I won't give a second chance and would cut ties (absolutely no contact) if the reason for break up was among my deal breakers (eg physical violence or getting another girl pregnant). Whatever fault the person has, I would assume it'll only get worse once married. I won't take the risk of working things out thinking that a person will improve or change.
