I'll admit that height IS a thing for me. I'm 5'9", so in my favorite heels, I'm over 6'1". My previous LTR was 6', and there were instances where he'd ask me to not wear my highest shoes because he didn't like that I was taller than him. His insecurity was the issue, not his height.
Last year, I dated a guy who was 6'9", and I couldn't keep my hands off of him. I loved feeling petite around him, something that doesn't happen that often for me.
My current guy is a smidge shorter than me. We had known each other for months as friends first thanks to mutual friends. We learned that we had lots in common but we were each in relationships but kept things strictly on a friend level. When we both got single, he told me he was interested in more and I had to confront my biases. He didn't meet my preference for height or type of job or taste in dress, BUT he knocked it out of the park for the important things like honesty, work ethic, sense of humor, fidelity, spending habits, hobbies, and ways that he shows affection. So although he isn't my typical type physically (nor am I his), things are going really well. We both placed the priority on the personality traits over the superficial physical things, and so far, things have been really easy.
