It’s my sibling
They like to push-pull. Friendly one day and cold the next with no clear reason why. Very very low self esteem and poor mental health, it seems they feel they are being attacked by everyone (family, friends who are well meaning) but they are always the victim of any situation or fall out. Somebody else has always wronged them and if you diplomatically suggest anything otherwise then you are gaslighting them and invalidating their experience. Outwardly extremely confident and assertive and enjoys to just talk about themself, glazes over when there’s mention of anyone or anything else. Likes to appear like they are doing very good and helping others but this is just to be seen by others, if nobody’s watching they are nowhere to be seen.
What’s going on here? I’m trying to persevere with developing a better relationship with them even though I find it wearing and draining. I want to be present in our niece and nephews life and it’s nicer for my parents if everyone gets on.
Thanks.
