Why are men only attracted to the bubbly and sweet personality?

That's an easy question as to why most are. You're more likely to fall for someone that makes you happy. Human's are social beings, so when one is shooting out a certain mood, it can affect others and make them feel it. And people have every right to be attracted to what they are, it's not everyone. Personally, I used to be attracted to that even just a couple years ago, the real affectionate type. Now, I go for intelligence, and a good moral compass. Personality type means rather little compared to those.

I haven't paid much attention to looking for people＜I mean friendships＞~People who are on the same wavelength found me out.Sure people who misjudged my personality also noticed me, but keeping in contact with me is extremely difficult due to my being detached and my passion for solitude.All old friends of mine are weirdos of weirdos.

I don't think guys only seek out that kind of personality. People want different things. My preference is someone hardworking and with a strong character. I don't think I could deal with a pushover.

Im down for a tsundere as long every now & then she appreciates me. For example letting me put my head in her lap and sleep or have some deep romantic vibes.

Wha? I hate bubbly and sweet personality.. they are annoying! But then again, i might be a tsundere.. who knows ¯\_(ツ)_/¯

"Bubbly and sweet", well are you going to fault men for picking that over someone who's aggressive and bitchy? I would pick the former in that case, but if you ask most men, "bubbly and sweet" won't be their first choice in personality either.
