girl friend

i am wanting to have my gf fucked by another guy i have told her i wouldnt mind if she did and her response was that she didnt think she would do it but didnt flatly say no either we have discussed this in detail and ive told her i loved her and if she did fuck another guy that it wouldnt make me love her less etc and i told her never to feel guilty about it, anyway this will be set up with another guy i have been chatting to on an adult website in the last couple of days, hes a mortgage broker he is going to meet with her to chat about a new home loan etc that she is after , hes good looking,athletic, im just going to say my friend put me onto him etc.
Hes going to try and seduce her over a few meetings not straight away so she doesent think something is not right.

do you think this a ok way of seeing what her response would be?
