Family Advice?

Cara
My husband and I have as little of a relationship with my mother in law as possible. But the moment we announced we are pregnant she has started butting into our life after not talking to me for more then a year and barely talking to her son. We want nothing to do with her but can't get away because of other family and how close we currently live to her. Does anyone have experience with something similar? Any advice to offer? Our reasons for not liking her are very valid and are not something we can put aside, but I don't know what to do.
