My mum (55F) left me (30F) with my grandmother and moved to another city when I was 4 years old. She got promoted and relocated. I'd see her for 2 days every 2-3 weeks. My dad was already living in another city following their divorce when I was 8 months old.
Thanks to her high paying job, she managed to buy 5 properties. Over the years, the narrative was 'I had to abandon my little girl, but I built her a future. The houses will be hers.' as I'm the only child.
Fast forward to 5 years ago, she retires out of the blue and starts travelling the world. I supported this fully as she worked hard. She has money coming in from her rental properties and owns the house she lives in. She has a very good pension coming every month also. She got a big chunk of money when she retired as a side note. But with the rate she travels (4+ long haul on top of 5+ smaller trips in a year) she's fast running out of money.
She put one of her houses on sale. Didn't even bother to tell me. She won't stop after selling only 1 either from my chat with her. I understand it's her hard earned money and she can do whatever she wants with it. But I can't help but resent growing up motherless for absolutely no silver lining coming off the back of this.
I have been working since I was 18. Never relied on her, to be frank never fully trusted her. I'm about to buy my own house and have a good job. The point isn't that I was waiting for that money, it's just that I can't stand now her narrative changed as it no longer serves her.
This is affecting my relationship with her as I find her selfish. AIBU? If so, how do I move forward/shift my perspective to still have a relationship with her as I love her?
