<human>: For me personally pursuing a girl who is already taken is just unimaginable. Regardless of their attraction, if that person was taken or seeing someone, I would drop my interest in her respectively. Maybe it's from an experience. I had a bunch of experiences where my ex's and current gf was hitted on by guys who I know(just their faces) and they are fully aware of that she is with me and would still try to get in my girl's pants. And it really annoys the shit out of me. Plus in some level, it sickens me.

Although there were some cases when I confronted them, couple of them told me they already had a crush on her long before I even started to dating her. I guess I understand this much. If that person you know is the ONE for you(like a soul mate) then I guess you won't be able to resist your temptation and still pursue that person.

But for people who are not in that case. Why do you do it? Why would you still pursue or even let yourself do things that may ruin that person's relationship?

Please share your thoughts and experiences. Thank you.
