Hey Guys, need an advice from you.
I met this girl on facebook (common friends; we meet once at a friend's house for like 5 minutes; she is a 9; I'm a 7 maybe 8 in a sunny day

). The issue is that she is in a stable relationship. Unhappy but 2-3 years old so pretty stable.
We've start talking on FB, I've follow the routines described here and everything went great: I got a first date (two days ago). The date went also well: we had great time and we kissed. Yesterday evening (one day after the date) I got a message from her saying that she had a great time with me and she likes me very much. But she doesn't want to cheat on her boyfriend nor she can dump him now. So “we can't continue like this ” (have no clue what she mean by that) but she would like to keep in touch (=keep talking). Since that message she texted me few times more: small talk about food, weather, job etc. I've responded laconically and not to all messages.
I do like her a lot and looks like girlfriend material but I don't know if there are still chances to take her and how should I proceed. Any advices?
