I had a little read on her old blog before it was taken down.
Seems like they are always quarrelling every few days, but after a
few hours of the quarrel, the guy will humour the girl, and all
will be ok again. And seems like although she "love" him very much,
she mentioned that she got a limit to all these. But the blog entry
that I read was in end 2005.
I feel that if you are unable to stand what the person is doing and
is making you unhappy, ending it early rather than late is a good
choice. But from the old blog, they were together for like 2 years
or more, so for her now to speak such a thing against her ex bf, it
like she is taking this chance to back stab him.
