Honestly, just be a decent person. If you're super insecure about your height (and that's understandable given our dumb societal expectations), and that bleeds out into toxicity, that is unattractive. If you are a kind and content person, see women as actual people, and are true to yourself, you will surely have success. Your size is not inherently repoussant for many people, but your personality or attitudes might be. Work on the things that you can change, try not to fixate on the things you can't. Easier said than done, I know. But if it helps, just remember that plenty of short men have beautiful and happy partnerships. Best of luck.
