Let down his 3 year old daughter this weekend?
So now he won't see her for another 3 weeks, making it 6 in total!
'We' had an argument on the phone the other day, he sent me divorce papers on my first day in a new job, knowing I couldn't get to a solicitor as its full time and knowing I can't afford it! 
I politely asked him to withdraw them as we are not in a position to get divorced, he agreed. Then two weeks later changed his mind, was very abusive about it and we fell out.
Today I received a letter from him, telling me he couldn't come to see his daughter as he couldn't find 'suitable accommodation'! It took me five minutes to find a luxury B&B near to me for him to stay!
He finally phoned me back and this is what he said 'in future you will think twice about dictating to me, this will teach you a lesson and its up to you to tell our daughter why I'm not coming up, its all your fault'! WTF!
I was distraught, told him I will go elsewhere so he can stay here, I apologised and begged him to come to see her, she is desperate to see him, crying for him etc. He kept repeating this will teach you a lesson, unlucky, its your fault and he admitted he is not coming to punish me. He can't see its her he is punishing 
I can't stop crying at the thought he can do this to her, he has two kids with his other ex wife. She made his life a misery, told his kids he was a shit dad, he didn't pay for them etc. She ruled our lives for 7 years, yet he took it all from her and never let his kids down once. I got angry rightly so and he is doing this to our daughter to punish me? I have never once stopped him from seeing her, I've let him stay with me to save money, in fact done everything I possibly can to make things easy for him!
WWYD? Where do I go from here?
