Trying to keep hope alive

[scared n alone]

Well, we were doing well this week. Tuesday, we had a nice back in forth when he picked the kids up. Friday, I collected some things I knew he would want to have for when he pick the kids up for an overnight. This moring(Sat) he is supposed to bring the kids back at 12. Last week He wanted to keep them till 4 and i said ok. He texted me today and said "i'll bring them home at 4". I replied we have plans please bring them back at their normal time. Then all hell broke loose. texting back and forth until i finally called him. He gets all mad because he thinks that i am saying 12 because i am being mean. I explained we have plans and you can't tell me 2 hours before you bring them home your keeping them longer. He then throws at me that when we go to court, the judge will give him 50/50 custody. I said fine. (is that really true about 50/50 custody??? any insight would be appreciated). Until then, you walked out and I have custody so it is what i see in the best interests of the kids.

I was doing so well with the 180. Did it all get screwed up. I am so afraid to make him mad that he will NEVER come back. However, I don't want that person back anyway.

help!
