When DP and I got together (4.5 years ago), he would often disappear when we argued. Just leave the house and come back the next day. I made it clear at the time that this was a dealbreaker for me, and he hadn't done it again since.
Until last month. He slept in his car in a lay-by all night after an argument, went to work, and then came home the next evening.
We have argued tonight on the phone, and he ended the call with "I don't want your dinner, see you tomorrow". Now won't answer phone or respond to texts. I suspect he will stay out all night again.
To me this is a horrible horrible example to set for DS aged 11. He is older now and aware of what's going on and it makes me feel like telling "D"P not to bother coming back ever!
Is this behaviour ever normal or acceptable?!
