in cases like this men the first thing is that you need to think about every move that you gonna do, ok ? you need to think how you gonna say it, be sure about what you gonna say so you dont have to look like the dump guy in front of her, so if she ask something about what you talking, you can easly answer , show always the truth, give you opinion becouse you are a good friend of her. i say this becouse i cases like this if you are not sure about the source of information, you will be sooooo emberrased and you gonna loose her friendship for a while, so thats why i ask you to be very careful talking with her about the problem.

but let me tell you something so you can remember this in the future, if you have a friend (girl), and later she have a boyfriend she gonna spend more time with him the first 2 or 3 months of the relationship, couse this is the pretty-pink-lovely part of it, then the things change couse is not the same passion, and theeeeen she realize that she need space and start spending more time with the buddies, but is not like this need to happen always, but almost happen. try to use her shoose! would you spend 2 hours with your buddies and 30 minutes with your brand new girldfriend?, thats insane!

and men, im soo agree with you, i would be soo angry too, having a good friend and then she change our friendship for a boyfriend? i understand you, but if you are a good friend too you would have patience always, remember that.
