Maybe I am lucky, I have two last names. Never went by Mrs Anyone but I kept reinforcing two last names put that together with an unusual first name and well you have me in a nutshell.
It is fine to not like her. She did a very hurtful thing to you. She probably sees it as doing something for herself. Always two sides you know. So do things that help you to distance yourself enough to keep you feeling good. When you do things for her, I imagine she feels as if you will always be available to help her and then she can go right back to treating you badly.
You may justify it as doing a good thing like you would for anyone. The problem is that she isn't anyone. She is your ex. If it is something to do with the kids, I can see that as a bit easier to take. Plowing her drive isn't your problem and this is why. She needs to make those adjustments in her life like any single person. She will never have a chance to see how good you were fir her if you keep doing this stuff. She won't have a chance to miss you as you are always there to rescue her.
Just some food for thought. Kat
