I have a close friend who went through a break up a few months ago, was doing very well and almost out of that when a long term friend of hers who she'd always fancied asked her out. She was thrilled and they were even discussing marriage, kids etc within a few weeks of dating, lots of apparently open and honest chats about life and being very vulnerable with each other.
Except, little while ago he pulled the plug on it and said he wanted to go back to being friends again, it was all happening very fast (even though all the long term marriage/kid conversations were instigated by him) and maybe see if something else comes of it later down the line.
What do you think is going on here? and what would you advise her?
