Mother-in-law

Nay
In the past my mother-in-law has accused my husband and I of not talking to her and letting her know what is going on with us. Do throughout our struggle trying to conceive we have been keeping her in the loop. My husband and I recently made an appointment to go to a fertility specialist because my Dr has done all that he can for us. In a phone conversation my husband brought this up to his mother. She wanted to know what we were thinkingg and hopes we don't do off because she doesn't believe in it. She feels that is like playing God. He didn't tell me this till he was off the phone, and we haven't spoken to his mother since the conversation. I'm a a loss for words... should I let her know that this upsets me or should I just let it go. This discourages me from talking with her about anything. We already have a rocky relationship to begin with.
