I would think if she was trying to cut ties with you she would just tell her mom not to ask you for any more help. Do you mind helping her mother out? If I were you my response would have been "I appreciate your concern but only I can determine what I do and do not have time for." If you get your wife a mothers day card I would try and find one that was more on the funny side than the really sweet & mushy. My husband always gets me one on Mother's Day too. If he didn't, I will admit my feelings would be a little hurt. Mostly because there is no better compliment to me in the world than to be told I'm a good mother. Especially coming from my husband. So I say get her one because regardless if you guys stay married or get divorced, she will always be the mother of your child and to me that alone is reason enough to show her appreciation on Mother's Day. That's only my opinion though. I'm sure others will disagree.
