you got to stand for something or you'll fall for anything.
What is it that you stand for? What do you believe is the right thing to do in an r? What is your job descripton as a girlfriend as a wife?
i think your xh is wanting to know if you've learned that commitment is just that and not feelings.
My mc said: Love is a verb (your actions communicate love), Love is an attitude (you do the right thing despite how you feel (such as the temptation to have an a...this is a feeling but the right thing to do is to be committed to the one you are married to) and Love is a promise to your spouse that you can either keep or break.
H wants to know that you see commitment to him as through better or worse, in sickness and in health....not something to be thrown to the wind when someone else takes your fancy.
That is the CHANGE in you he is seeking....a woman that will stand firmly by vows cause it is the right thing to do.
We all as spouses mess up, do dumb things, but the commitment to the r should go on despite arguments or whatever. That is what db'ing is all about...d is not an option.
