I have a weird attractions

I just had a crush on someone just by knowing them for 1 day , I hope this doesn't sound weird, I've always had an attraction for people that are vulnerable and weak and i get more attracted when they say they have no friends or are easy to manipulate. I never manipulate them but I get this sense of guilt when I'm upset at them , like how sorry they are , it makes me love them even more because they can take my anger and because of how timid they are it's that you do an effort to try to get a word or two from them, this person I'm in love with and I'm willing to spend time with them and buy them something , the thing is , our conversations are super dry , and I don't want to sound awkward. But they always check on my profile every second , and they seem like they're interested and want me but at the same time they're distant or timid , I do from time to time sneak a flirty message and that makes them open up abit, I've seen their face and they call themselves ugly or fat and I feel bad because I find them super duper attractive , I'm not "in love" but I'm also fantasising about them. I feel like this will grow and I'll become obsessed.

I've got rejected alot so I'm careful and I barely text them and when I don't , they check on my profile alot .

I needed to get this off my chest so sorry
