What does it take to fall in Love?

I hope that doesn't make me look by any way a weirdo , well am a 22 years old man who likes to think of himself as someone who succeeded in life till this point thankfuly , I have my own house , my own car and even my own small business , I had quite a few relationships in my life and it really doesn't turned out to be that good , am a bit not social to be honest but am a 6'6 man who worked as a model for the last two years in college , I maybe a bit more serious about relationships but that doesn't make me a bad person as I've been told , and to be straight, I never actually fall in love ! That's weird I guess in my last relationship I treated my partner as well as I can do with everything I had I tried my best? Am good with numbers I can cook I did almost whatever advise I that I could had my hand on but finally we still break up , and basically it becomes like a limbo to me with the same story but with different partners and better situation for me for 8 years now? So am looking for some advise some experience that may helps me understanding what shall I look for
