What makes someone cheat?
So, there is this girl, she has been dating this guy for almost 4 years and they just moved in together (I could tell she has become less happy with it). I have known her for almost 3 years as her superior. We are no longer in a work related relationship, and she is still dating her boyfriend. This past week however, we were on a trip with some friends and she slept in my bed one night when we were drunk, we kissed but did not make out and I told her I had a crush on her. The next night we had a few drinks and literally followed me to my room, we hooked up and she slept over again. Now on the travel back home we talked about what we felt and how we wanted to keep this going. We even kissed when I dropped her off in front of hers and her bf's apartment.
After I dropped her off at home, she texted me and said" It's not the same...just a side note". I am guessing she is talking about her feelings toward her boyfriend before and after the trip?
My question is what makes a person cheat? She has never cheated on him before. I feel awful, but I have also liked her for a year now and feel like I had to give it a shot, does this make me a complete , should I just tell her to forget what we did and to be with her boyfriend? Even today we have been really flirty. Do you think she just wants to hook up on the side or actually kind of likes me and wants to take a chance and leave her boyfriend?
Just wondering...
