I have name changed for this. Today I was visiting my DM (hadn’t been there long, I had checked she was free and if it was ok to visit before going). Rude relative (RR) arrives unannounced. They come in and say its only me. I greet them and say hello X how are you? I was totally blanked. This isn’t the first time they have done this so openly. I usually let them off with this. But today I called them out on it and said are you not speaking to me or something X just I said hello to you and you ignored me. They sat down (totally ignored me, turned their back to
me and began a full on conversation to my DM and my DBRO) and behaved like I hadn’t said anything and I wasn’t there. DM and DBRO seemed oblivious and were all over them (I felt like a spare part and totally surplus to requirements). We were having a three way conversation before RR arrived. RR was so full on talking to DM and DBRO about a situation and people I knew nothing about (RR wasn’t upset this is just what they are like, and how they behave likes to to hold court and be the centre of attention most important person in the room etc) and barely pausing for breathe. So I couldn't get a word in.
I haven’t seen this relative for a few months. They are younger than me and they have form for rude behaviour towards me. DM and DBRO didn’t appear to notice. I waited a few minutes then made my excuses and left. I said bye to everyone RR didn’t even acknowledge that I was going or say bye. DM texted me afterwards saying it was nice to see me and that I didn’t have to go just because X came in and that X had spoken to everyone when she came in. I didn’t bother defending my position or saying about RR’s behaviour as they have made their position clear in the past.
What would you do DM always defends RR and because of RR’s shit stirring my relationship with DM has become strained and difficult.
