guys I your advice, I got this girl I like in the office, she doesn't know me at all, we have this chat messenger in the office so I took the advantage of it. I said "hi" and I introduced myself, I notice that she has a tattoo so that's were I expand the conversation, then we became comfortable and get into the part about no string attach thing, she said she agrees and said that we might just get along, and then I ask her for her facebook account and she gave it to me, after that I jokingly tell her "are you sure I can add you? someone might get angry?" she said " as long as we keep it a secret he wont" so from that time I knew she has a bf, I showed her my picture through chat and she said " ohh I know you" from then on we agreed that I will visit her apartment and I will bring some dvds to watch. on that scheduled day I reminded her about our plan.. all of a sudden she said I cant cheat on my bf.. I realize that's how much I love him. she admitted that shes always the cheater in the relationship and all.. but I know she wants it.. so any advice what to do next?

sorry for my English.. and I know it may not look right it some other people but for those who thinks what I should do next please I need advice in getting that chance back. thanks!

Doubling up i see, tryna shit where you eat and get w/ a girl who is in a relationship. Whatever floats the boat.

Stop messaging her and just go up to her in person to invite her out for a drink. "Yeah we were going a lil fast over messenger, you seem cool tho, lets just grab a drink and get to know eachother a bit."

With the next girls, don't bring up a possible boyfriend, thereby handing them a reason to flake on a silver platter.

Also it is entirely possible that this girl is single and available. Bringing up the "do you have a bf" plays on a woman's pride and they will go along with it more often than not so as to not be seen as undesirable.

Sounds like shes having second thoughts I hate that. Happened to me this week with a chick that lives 2 HOURS away luckily I just started the car when she changed her mind but im still giving her the D later this week.

Like you said she still wants it if you guys go on break at the same time try to escalate there remind her what she's missing out on you dont have to literally say that but im sure she will think that. Hopefully the next time that day comes and you call her she's in a different mood you can even joke around about it and try reverse phycology and say "I hope you don't use me and throw me away when your finish". That may work and make her want it even more of course it isn't guaranteed but its worth a shot.
