Really don't want to dripfeed but the backstory with MIL/ILs is massive and I've posted about it before under another name but think SIL may have cottoned on to the previous name so don't want to link to it. Far too much backstory to write here but in a nutshell MIL in particular has had a lot of hissy fits in recent weeks/months and caused a lot of stress for us, DP especially. Said lots of very hurtful things, triggered a lot of guilt and worry for DP.
Recently it all came to a head because I wrote her a huge email being civil but basically saying she was out of order (with DP's blessing, but he struggles to confront her unless the situation is in his face) and I think MIL realised she'd gone too far and went back on a lot she'd said and was as nice as she could be to smooth it all over. DP desperately wants to believe it's all sorted but I've got a feeling she just realised she was pushing DP away and did the 'reformed' act to keep DP on side, as he was determined to 'choose' me over her if it came to it and I think she knew that.
Part of the whole problem between MIL and us has been that she can't let go of DP and still wants to mother him - she tells him what to do and wants to keep control over the decisions he makes. This isn't me reading this into it, DP has said it himself and even MIL has said similar but said she's working on it
. DP's last relationship had similar problems - his ex told him she didn't feel he supported her over his mum, so it's something quite historic, not something I'm reading into the situation wrongly.
In the 'getting it all out' conversation MIL said a few things that DP took as quite nice, reassuring him that she cares about him, but I read very differently into them and took them as veiled attempts to 'put me in my place'. She said I didn't understand DP like she did because she'd brought him up (and because of previous comments she was replying I know she meant I was wrong about her having hurt him), that they are very close and their relationship is unshakeable, that after being a mother for so long she knows what she's talking about, that nothing can come between them, that a lot of what I said wasn't accurate (about her having hurt DP with her past comments), that she 'knows she's put too much of her life into her kids and is trying to cope with not having them anymore' and how she'll always be his mum (true, yes, but following the rest it seemed off).
I can't help thinking those comments aren't normal and she's saying 'well I might be doing the nice and lovely act now to keep DP happy but I still expect to be the number one woman in DP's life and I'm going to cause more havoc in future if you don't roll over and let me' - am I overreacting?
