If she is sending out a feeler about a possible reconciliation, how hard are you willing to work to make the relationship work? There may well be compromises that need to be made. A compromise entails concessions on both sides. Are you willing to make concessions?

I guess what I am asking is whether you agree changes will have to be made? The way you two related before did not work. What will? Maybe it means therapy? Are you willing to consider therapy?

Good luck in whatever way you choose to go.
