I have an ongoing situation with MIL and its very wearing. I have fertility problems, in the last 6 years I've had an ectopic pregnancy, multiple gynae surgeries, 4 cycles of IVF and a second pregnancy a couple of years ago, but had to be induced in my second trimester as the baby died. I'm now 40 and realistically I don't think I'm going to have a baby. It's painful at times but am coming to terms with this.
My MIL hasn't grasped the concept of this. She continues to pull me to one side and offer anecdotal advice on how her friends got pregnant, offers facts she's read in the daily mail or suggests crazy things like paying a pregnant woman from the third world and adopting (technically kidnapping!) a baby. It's a topic she never approaches my DH about it. All the responsibility seems to be on me.
In the past infertility left me feeling invisible and empty so I made a lot of effort to make my life more fulfilling in other ways. I changed my job, made time for things that make me happy and have close friendships. I don't think MIL sees any of this. I think she feels like DH and I have an incomplete life. She is incredibly maternal and is always talking about her nieces and nephews babies and showing me (but not DH!) baby photos.
I was approached again this weekend about how I might be able to get pregnant by taking some sort of herbs because it worked for her friend. It just made me feel horrible. DH is so supportive and has told her we probably aren't having a child but I don't think she can accept it. She is family and most of the time a kind and lovely person, I don't want to avoid her but not sure what else I can do.
