Taking a step back-a fresh start

[cbtdad]

I try to not get to ugly or anything when I text W at moment, but it is so hard not to do. I am so angry and I want to just go off on her. Once again I want to, but I won't because it won't accomplish anything.
She did text me this morning to let me know her mom would not bring son up there today or tomorrow. I already knew this as about 30 moms before that I saw her mom and asked if W had asked her to bring son up there. MIL said, "she asked but I said no. She made it clear he doesn't want me to go to horse show, but expects me to bring her son up there. I don't think so. She's not going to use me like that" was happy to hear MIL say that. As bad as I want son to see his mom, I think it is just enabling her.
Anyways here is text exchange with W, tell me where I messe up:

W: talked to my mom, she said no

Me: K. [censored] for son, but I don't blame her

W: well come up with an idea. WC?

Me: My only idea is for you to come see him when you're done today and go back in the morning. I really don't know what else to do. I'm very upset about all of this right now W

Me: It's your responsibility to come see him. Not others responsibility for others to bring him to you. I was very supportive of you getting ready for this local show. But I guess a local show makes no difference



No response to lasts texts. That was an hour ago.
Anyways, I know I shouldn't have responded with some of the things I said, I'm just trying to do my best not to completely lose it on her
