Okay - clearly I'm not an expert on this topic. If you've read previous posts, you know that I was in a relationship I believed to be serious - room for my stuff in his bathroom, met the parents, met the friends, etc. - and it wasn't.
But in my defense - when people say these are the signs that a relationship is getting serious - what's a girl supposed to think?
The moral of this story, I think, is that there are no rules in dating - and you should always just be very clear in your communication. Don't assume that just because you start spending Fridays in, that you are getting serious. There's no formula, no one set of rules that applies to every couple.
Just two people, finding their way to each other, at the right time and right place.
Still - never, ever, be afraid to argue.
