Searching4 - I started seeing a bit of charming monster about 10mths post BD. Before that it was all rage and everything was my fault.
Angry monster showed up many times in the first 18mths post BD in particular, and still makes occasional appearances.
It took me a while to wise up to it - but charming monster (flirt) appeared whenever we were in public together - such as a school event, or if he wanted something (something signed for his advantage). As soon as the event was over, or he got what he wanted, he would return to being irritable and distant.
It wasn't until I found this site some months later that I had any clue as to what it was all about.
