TheUF - Changing gears - Dropping the rope?

Doing something I shouldn't, hoping to achieve what I need

(She disrespected me, but still took it for granted I would help her)

By accident my X's washing machine was thrown out a while back so I told her I would buy her a used one. I also told her I could deliver it to her place. She's been sick so it hasn't happend yet.

I've been sick the last days and have been home with S for the last two. Which worked out OK for her as she had lots of errands to run. I told her yesterday that probably I would deliver him today as I was hoping to be well and leaving for work tomorrow. Well this evening the fever kicked back in and I won't be going to work. I sent her a txt saying I could have him til tomorrow when she got off work if that worked out fine for her as well.

A couple minutes later as I was changing diaper, she called. Crancky and disrespectful. She asked if I could be there when she finished work and I said yes. She kind of puked a goodbye out, and we hung up.

I called her back when I was finished with S to tell her if something bothers her she can tell me b/c that would be more helpful than just being passive agressive.
I'm not going to help her or anyone else do something if they disrespect me.
She basically went into R talk mode, and I....yes...joined in. D@MN it. I was calm and tried to be in the passive side, but didn't kill the convo when I should have.

To sum it up:
(my replies in red)

**She needs a washing machine, now. I know, I bought you one, with guarantee, I drove it to your place but there was no one to help. You should feel happy about me buying you one, I owe you that. However I don't feel I owe you to get up from bed, sick, to move it FOR you with no help.

**She was angry that everything worked out so good for me and not her.
(WHAT?! I certainly don't agree lol) "Sorry you feel that way about it"

**She was, just angry. Annoyed. When asked why she said no reason, she was just annoyed by me as a person and annoyed at the way I am as a person. Always has been. That's why we don't get along, why we are not compatible and why things has been that bad all these years.
Ouch! Below the belt! Believe half of what they say. She wanted to marry me, she wanted to have kids, said I was her life etc. "well, I find it hard to believe things were that horrible as we were together for quite some time and had plans ahead" She just replied she didn't say things were horrible, and brushed it off.

**She didn't care how we talked to each other or if we argued, as long as it didn't affect S. The thing is, if we can't communicate better than this, it WILL affect S. She brushed it off.

**She says there is NOTHING, absolutely nothing, about her she needs to change and especially not for me. We both have things we need to change about ourself, but no it's not for ANYONE else, it's for ourselves as individuals.


**Today she would have had help with the machine. She had wanted me to deliever S today, as she didn't have any errands to run tomorrow so there was absolutely no reason for me to have him. Except the fact that I'm his father, he's my S and I love spending time with him? She swallowed her words and stalled a bit. Also, I asked you precisely "IF it's ok for you as well. And you said OK, you didn't say anything against that. Brushed that off as well.

Look, I didn't call to argue or get trash talked. I just wanted to be clear and not have a underlying issue here. she replied "I didn't expect you to call and I didn't want you to either." Well ok, bye then.

Wow. Yesterday she said she was sorry for replying to my txt so late(hour later). She had smileys in it. Last time we spent time together it was just dandy.
Now, this.
I know...stay out of R talks. Still, this was an unexpected response to it.

Is this normal behaviour for a WAS? Guessing it might be.
Still, it makes me uneasy. I don't know if this is the kind of instability I need in my life.
