Not sure where to start with this, to be honest. As a little background context, I'm in my 20s and live a flight journey away from my mum.
I've never been especially "close" to my mum. Our relationship has always been what I can only characterise as rocky. I'll have times where I feel like I can trust and be open with her, only to later recoil when she behaves in a way that damages that trust I thought we'd built.
My mum has a tendency to say exactly what she thinks in the moment, regardless of whether it is inappropriate or rude. Not necessarily in public. But she'll definitely say it to me, about me, or my friends, family, etc. She always acts on her emotions, always. This is key, here.
So, the most recent, ahem, "disagreement" was a few days ago. My partner, whom I live with, went to visit his family for a few days following the death of a direct relative. DM began making remarks about DP being gone a long time, and that he had "left" me on my own. I quickly clarified that I was perfectly fine, and that DP was away for a very sensitive reason, and should be with his family at this time. Quite frankly, this was absolutely none of my mum's business. DM then swiftly turned the situation onto herself, stating that no one was around to support her when so-and-so died in her family, etc. I bluntly told her that I felt she was being insensitive. She went on, making comments like "well I think he (dp) should have spent more time with - (relative) when they were alive". At this point, I was feeling really disappointed and shocked at her comments. I told her so, and she began acting like I had hurt her so deeply, that I was treating her so unkindly and unfairly, etc. Insisting that I don't care about her, no one cares about her, etc. This included comments implying that she cares about me more than DP (based entirely on the fact that he was spending a few days with his family?!).
Needless to say, by the end of the conversation, I felt absolutely drained. Emotionally and physically. I really don't know how much more of this I can keep taking from her. I would never tell her, because God knows I love her, but this time I've had enough. It's hard to know what to do, going forward. I feel so hurt and disappointed by her when she starts acting like this. But this time is worse - I just feel empty.
