I'm aware this is going to sound petty but think of it more in terms of many, many very little cuts rather than a single deep gouge.
I have a newish friend and we are very similar in many ways.
She and her husband recently invited us to stay for a few days. My partner has only met them briefly a couple of times previously and this is the first time he has been to her house.
He was very effusive about how much he loved their house and even commented on, of all things, a vase he really liked.
It wouldn't be so bad if she and I were very different, I don't think, because there might be genuine style preferences but she and I are so similar that our houses are decorated and styled quite similarly too. Nothing in either of our houses would be out of place in the other and there were a lot of quiet, "I have one of those!" moments. He's never commented positively on my house. Never negatively either, he just doesn't notice stuff. He certainly wouldn't have an opinion on a vase I own.
I don't know, I struggle a lot with not feeling good enough (after a life time of being told I'm not good enough by one person or anther) and this just felt like one more thing where I'm not good enough.
I know people say comparison is the thief of jy but its not me doing the comparing. I loved her house too. But I also love mine and, anyway, they're not in competition.
This obviously isn't the only thing and probably does sound quite petty but it really consolidated how invisible I feel in my own life, my own home, my own relationship etc and that's the real problem.
