2nd time around part 2

[NotAgainPlease]

H sent a text yesterday about the kids 8th grade promotion. He said he's only heard from his dad and stepmom. I said then I'm going to give the extra tickets to family that needs them. He said hold on let me ask again. This is from his mother and sister who liked my H cannot make a decision to save their you know what.
I said I will give you until 5 o'clock tonight give them a deadline or I'm giving them away. ( please don't tell me that I should have given him the four tickets and let him decide what to do with them. We only get 4 tickets per child and there are other families who need them so I was trying to make sure he was going to use them all.) He text back later and said he will take them. He then said he wanted to see if you could have the kids Saturday night he was going to plan something for then. This means he's going to have barbecue with his family and the kids. I told him that I was going to take the kids after promotion to eat, my mom from Seattle will be here. If he and his dad and stepmom wanted to join us I'm sure the kids would like that. But I did not feel comfortable having a sister and his mom since they talk so much crap about me. He said that's why he was going to have something after for them on sat. I said does that mean you're not coming on Friday?(this was planned last week) H said no I will still come.
I'm not invited to his function but that is because I don't want to be around his sister and mother. I get that, this day is for the kids not for us.
However, at 2 o'clock in the morning last night I sent him a text saying I will spend Friday with the kids and you can spend Saturday with the kids and we'll do our own thing. He sent back in the morning sounds good to me.
I just have to make the break....I know I'm a slow learner..I'm trying...H knows I'll let him come. H would let me come too but I don't want to. But we would continue on like this and never get anywhere. This is how we ended up getting back together last time and nothing solved. We can't do it again without serious changes on both our parts.
No, we don't have a set schedule for the kids. Do to my H job he takes shifts that he can and he never knows when they are. I'm okay with that because he is trying to make money. It works for us.
Just journaling to get it off my chest.
