it had happenend to me in past, when a drunken friend of mine had a so called confession, but guess what, she wasn't drunk. Personally, i wouldn't mind marrying a Christan girl, since its not prohibited in Islam. as per reactions from her BF, it shouldn't bother you cuz that's her problem, let her deal with him. if she is getting serious with you, i think a good practicing Muslim can fix things, such as setting a good example to quit drinking n stuff. my suggestion'd be to have a serious discussion outside work at some dinner or lunch and find out what she is looking for? a serious relationship or a friend with benefits!
Good Luck!
Thanks bro..I am glad to see that someone can relate. Right now I am keeping my distance but feel pretty bad about it because its like I shut her out completely after that Friday.
Bro, the problem is that I am not sure if I have the capability to fix things like drinking etc. I mean I live my life and let other do the same. I mean its not shes some Mormon chick so things would be a bit easier in terms of lifestyle. I'll see how things go after a period of cooling off.
Besides I am on a new project and looking forward to it!
