Thanks so much crazy. I have read some. I need to go back and re read some of my textbooks.
The ignoring him isn't working so well.
So I have started to just text. Basically for several reasons 1- being it is short and to the point. 2- I have no tone or any way to convey anything additional.

Basically today they came out and turned my gas on because we have gas heaters. There is a heater downstairs and one up here.
It simply wouldn't come on. I tried and tried. Finally, I broke down and sent a text. Verbatim it said "Are there additional gas valves I need to turn on besides the ones under the heaters?"
He called me. So I went outside to look at everything and it seemed normal. Then I tried both heaters again- bleeding the lines. Nothing happening.
Sent another text- "It is not working. No gas is coming through either heater. Can you look at it tomorrow night? I would appreciate it."

Tomorrow is Tuesday which is the night he stays with kids while I do my clinicals.
So no problem he can do it then right? And I get to avoid contact. Wrong.
He calls. Questions me about the gas. Of course, I do not know. So he says you want me to come do it tonight? I responded- Tomorrow is fine. Don't worry about it. It's not that cold. I don't think we will even need them. He pushes back- I can do it tonight- It's no problem I don't mind. Finally- I said- it's up to you. Either way is fine with me.
So of course he will be here tonight. Never mind the fact that he told me in our argument just yesterday that he didn't want to see or talk to me. Fine. That is how we came to the agreement to text. I actively am trying to limit contact and he is insisting on it. It's the stupidest thing ever.
You think I should treat that as a boundary? I am thinking about it. Just saying- look we are supposed to be texting only.
I don't mind talking to him really but then he makes it sound as though I am pursuing him even if I am not.
One thing is clear- He has no respect for me at all. That is what irritates me about the calling bit.
So I dunno. No clue.
