My MIL just told me that my friend has spoken to her sister and said some awful things about me (they work together)
One of those things was that I got pregnant to trap my partner. I know my friend could never have said this as she knows I have had loads of problems conceiving. There were various other things that were very off the wall. Friend says she has never spoken to this woman (its a big place)
SIL dislikes me very much and is close to MIL's sister. She also used to work with my friend. I dont know if thats relevant or not 
Anyway, AIBU to think this woman made it up? Im just not sure I 100% trust my friend either.... I dont know who to trust in this scenario. DP is not concerned at all, which is good.
