Well first I need to tell you to be careful.
I've been on your side and I've ended up getting the "taken chick" and I have to tell you, at least for myself its always thin ice when you say you are beginning to "fall for her".
Look at the details:
Look she has been in a relationship for 4 years.
She is speaking to you and getting closer to you behind her mans back.
What she is doing is called "emotional cheating". You may be fulfilling what her man cannot emotionally right now. In other words, you are in the short end because you are the one being used.
Before moving forward, here is a word of advice my friend, look at it as a chance to get in, clear your head and get out.
If you fall for her, forget about friend zone, you'll be in wreck zone.
What do the vets on the forum think?
