This actually isn’t a AIBU, so sorry that it may be on the wrong board, but I’d really value some advice and support...
I’ve always had a strained relationship with my (female heavy) ILs, whereby I’ve often felt rejected and excluded by them, with the exception of my FIL, who has always been very kind to me. For the sake of my DH, however, and particularly for the sake of my DC, I have kept on making an effort with them over the years and now have an ok-ish relationship with most them, which I feel proud of for the sake of those I love the most.
One clear exception to this though is one of my SILs - think narcissistic PD and that would be about accurate! In my opinion (and I think in the opinion of most family members actually), she is someone who can be very unkind, mean and spiteful at times. (The worst occasions of this were in the run up to our wedding and during my DCs christenings, whereby she caused several issues that were very upsetting and hurtful and which I and many others still remember painfully years on). She is someone who likes to be admired and appears to secretly take pleasure in other people’s downfalls. For example, she enjoys being a martyr to family members when they fall on hard times, but as soon as they are back on their feet, she seems to hate this and becomes unkind towards them again. My personal experience of her is that she acts as though she is humouring me in conversation, but is actually looking down on me and will enjoy bitching about me and belittling me to anyone who will listen as soon as my back is turned. This makes me feel like shit. I feel like she goes out of her way to make me in particular feel incredibly stupid when I’m with her by how she talks to and treats me in front of others (I’m actually a dr, so whilst I might not be Einstein, I do have some level of intelligence and don’t normally feel so rubbish about myself). To be honest, my sense is that she’s only ever nice to me when no one else is wanting to speak to her or if it would make someone else who she looks down on feel excluded by talking to me and leaving them out.
Anyhow, this has been going on for near on 20 years and I really feel that for my own mental health, I need to stop this affecting me the way it does. Going no contact really isn’t an option and I’m getting much better about not feeling nervous before seeing her, but I just don’t know how to be around her to protect myself emotionally without causing a scene. I’m normally my own worst enemy, as I start out every meeting being super nice to her only to have this played out, or by sending her nice texts between meetings, only for her to briefly reply and then ignore me or not reply at all. I feel like I’m coming across as desperate. In an ideal world, I’d have a good sisterly relationship with her, but she obviously does not want this, so what do I do?! TIA!
