Oof, sorry to learn on what you went through. I hope you're in a better situation now.

I would have imagined part of "growing the fuck up" is forming a support network like a "found family". In this case, taking accountability of yourself means not outsourcing your emotional regulation to other people, but I don't see why having someone's shoulder to cry on is a bad thing if the moment calls for it.

And I do think it's reasonable for anyone to wish they have a positive parental figure in their life. From what I was reading in support groups of people with abusive childhood backgrounds, they tend to grieve on parents they wish they had (but never got), and it helped them move forward that they have a substitute parent figure to help them stand up on their own.

Getting back to the original image, the OP seemed to assume by default the straight dude is pathetic because of how he reacted to her house's interior. For all we know, she might have assumed wrong and the dude just likes those things because it jives with his preference.
