I saw one of my old friends for the first time in four years this summer, and I was completely taken aback by how attractive she'd become. We hung out several times before I returned to the United States. During that time, I developed a pretty big crush on her.
Fast-forward about a month; I'm talking to her a few times a week via social media. At one point, I asked her if she had a boyfriend and she said she did. He's two years younger than her (the age gap between her and I is slightly bigger). She told me he suggested marriage but that she turned him down for now because her parents wouldn't approve. My family is close friends with her family, but so is her boyfriend's family.
She's called me "very handsome" more than once. Her parents want her to get married to someone in the US (like me) but also with ancestors in that country (also me). We share secrets with each other, have deep conversations, and casually tease each other all the time; every talk is fun.
Recently, she sent me the "kiss" emoji and called me the most warm-hearted guy she's ever met. On occasion, she even compares me to her boyfriend.
Does she like me, even though she has a boyfriend? I really do like her, and I would love to be in a relationship with her, but I don't want to encourage her to cheat; it wouldn't be fair to me nor the other man.
How should I approach this situation? Should I pull out? I know enough that I shouldn't pressure her to make any decisions.
P.S. Where I come from, it's considered rude to touch a married woman if you're not her husband. That would be terrible for me; she gives the best hugs.
