I separated from DH a few months ago. We get on ok overall- still very civil etc.
SIL (his sister) however has suddenly taken to telling me how much she misses me and wishes DH and I were still together. When we were together, I found her insincere, sly and condescending so the feeling isn't particularly mutual.
She has managed to persuade me after many requests to meet up with her for a "catch up." I've been reluctant to go but decided I would after her latest round of buttering me up.
But.... during our last correspondence, she asked me if I'd be willing to do something for her family (for MIL and FIL) that woud put me in a very awkward situation potentially. I said no and explained why. I have since told DH what she has asked of me and he looked shocked. I then asked him why he seemed so surprised and he told me that she had already asked him a few days ago and he had told her no and requested that she didn't ask me. He then backtracked and made lots of excuses for her (as he usually does) and said it was her naivety. But I know how sly she is and know that this is not her being naive. I have witnessed and been at the end of her asking personal, uncomfortable questions to people which she already knows the answer to, seemingly with the intention of making them feel uncomfortable.
Then, I've also discovered recently, that she's been messaging my ex SIL (my brother's ex), endeavouring to strike up some sort of friendship with her, just because their kids are the same age (exDHs ridiculous excuse).
I've literally only discovered that she had asked my ex the same question she asked me this evening and I'm supposed to be meeting up with her tomorrow. I thought her latest messages had perhaps been sincere but now I'm doubting them and suspect an ulterior motive, whatever it may be. She's not been open and honest, not told either exDH or myself about having the same conversation with both of us separately and acted like she didn't know exDHs response.
Do I still meet up with her tomorrow? What do I say to her? What could her ulterior motives be? I don't trust her.
I also can't fall out with her as she's pregnant with twins and had enough complications already. I have to be careful not to upset her... it would be easy for her to paint me out as the bad guy so need to keep my cool.
