Search Results: single girls clubs

On Saturday i girl that i was looking at came up to me while playing pool with my friend and brother and she made sure i was on her team and she was a really lovely girl and i liked her and she liked me a lot but she told me that she was engaged to someone else for a year but she kept playing with her ring and wanting off and she said if it wasn't for the fact she was engaged to her bf then she would be mine.
and we continued getting know each other and we went to a club and we danced and played more pool and then she was flirting and holding my hand and i wanted kiss her but knew she was engaged. but the questions i keep asking myself are
1. do i keep pursuing her?
2. is cheating because i am single but she engaged?
3 . do i just be her friend?
4. do i leave her alone and do nothing?
5. do i let marry this guy because i really like her?

I have a friend (that's a girl) and we text all the time (I don't think there's been a day that's gone by since the new year that we haven't texted each other, sometimes she texts me first sometimes I text her first). Most of our conversations are random but we talk about some "deeper" stuff at times. We go to the same school (rarely see each other during school day) but we're in this same club and we hang out a lot, it seems like she wants to hang out with me.
other useful info: we are about 3-4 years apart (i'm older), we're both single, we just met last October
