So the other day before counseling appt for son W and I went to bank to safety deposit box. She wanted to get her passport and see if it had her maiden name or married name on it. After she came out she had it with her and asked where my wedding wing was. I jut said its at my apartment, she thought it was in box beaus she we out hers in there with all the moving.
Today she asks me to go to box to get marriage certificate because she wants to change her passport from maiden name to married name.
Says she wish she would have done it 5 years ago an says its a pain.
I asked why the rush, going somewhere?
She said no, just want to get it changed.
Anyways, why does she continue to ask favors of me!!
What do I need to get message to her that as long as there is OM this so not my job!
When we talked the other day she did admit that she relies on me for a lot. I told her it needs to stop because frankly i fill like I'm being used. She said she understood but still asks me to do things.
