I want to be with someone but my standards are too high, which is a good thing..???

On one hand I get really, really lonely. I do want partnership, but at the same time I do know what a good relationship looks like. This turns into a weird cycle where I don't get into relationships too early and I get my heart broken over and over again because of things that make relationships impossible, when I could've just done the dumb and young thing, which probably would've ended badly... So I don't really know what to think of it. Should I just do what my heart says or should I follow my logic and thinking even if it hurts?
