He has been off work this week and had the dcs Sunday/Monday night and Thursday/Friday night.
There was a huge kick up when he was collecting them Thursday. He were meant to be collecting them at 12pm. He texted me at 11.45 saying 'time had drifted by and he wouldn't be collecting them until 2pm ish'
He knew I had a driving lesson at 12.30...which is the reason he was coming at 12.
Anyhoo, he kicked up a fuss and arrived at 12.05...refusing to step foot into my garden.
By this time the dc where a little upset that daddy was in a bad mood (he hadn't had a drink) and he was struggling to fasten them into their car seats. I offered to help him and he turned and said 'fuck off into the fucking house you fat bastard, go on, piss off'
Now, this is not the first time he has said this in front of them.
From him turning up I was very upbeat, cheery, and said nothing wrong that he could use against me.
Since then, he has accused me of sleeping around already...not outright but in that sort of thing.
He texted me at 9.30 this morning saying he was on his way with them...much earlier than the time he said he would drop then off. So I had to take them both, on the bus, to do a shop, and get birthday supplies. Which was fun 
It is dd's birthday today and we were meant to be taken both dc's out to a wacky warehouse type thing but he 'forgot' to send the vouchers off. We had agreed that with her being young, we would still have both our names on a card and her gifts would be from both of us.
He has bought her a separate card and has bought gifts that well exceed mine and that she will adore.
He was meant to be setting up a standing order for me for maintenance but hasn't bothered doing so and I am worried now about his reaction when he finds out I know that I am actually allowed to claim Tax Credits.
Not sure what I am hoping to gain from this thread but just needed to vent.
