My future mother-in-law is starting to drive me crazy. She drinks to the point of being hammered every weekend, and because of this she constantly relies on us for help. The other day she called the next morning after taking a cab home to get a ride (from me) to her car. She didn't even directly ask me, she asked my fiancé who then had to relay the message to me. I tried to be as polite as possible saying no, but I really don't think it's my responsibility to drive her to her car after she gets hammered — she could just as easily have called another cab (she DEFINITELY has enough money). Now, if she had called me in an emergency or in a situation that was out of her control (e.g. her car battery died and she needed a jump, even if she was arrested and needed a ride home), I would have been there to help, but this was not an emergency.
Now since I said no, she has this really sour attitude towards me and my fiancé. She has been calling leaving nasty messages on his phone. She even posted on his ex-girlfriend's picture on Facebook saying how her picture was "so cute!" the day I turned her down (this was posted to my news feed on Facebook).
I'm getting sick and tired of this situation. Good news is we're getting married and moving far away soon. I have been trying to speak as little as possible with my fiancé about the issue because I just don't think it will do me any good to complain to him about his mom. He knows the issue and agrees with me on the matter — but the conflict has been bothering both of us. Any comments or ideas on how to handle this issue? Anyone been through a similar situation and have any tips/hints? Thanks!
