Time for an Introduction...and Thanks

[figure-it-out]

Hello,
I could use some quick feedback/advice on the following e-mail exchange between H and I today:

H - Did D tell you about Disneyland (H "generously" decided to give D $$ to go to Disneyland with her friend tomorrow) He of course won't be seeing her prior to that so he let her know that I would give her the $$ upfront and he would pay me back. All this was done without my knowledge until D told me that is.

M - Yes

H - Is that OK? If you need the $$ right away I can meet you and give it to you.

M - No, it's fine she may wait and go this Fri or next anyway

H - Oh ok, I told S I can't pick him up this weekend. I wanted to communicate it to you though.

M - OK

30 min later...

H - Are you mad at me?

I did not respond. 1 I was just getting into the car to leave work and 2. I didn't know what to say

10 min later...

H - Guess so

How do I even respond to this?? Ignore it? Say no? I want to say "mad, and I MAD"? H$ll YES I'm mad. I'm FURIOUS. I'm mad you're doing this to your family, I'm mad your buying your kids to alleviate your guilt and shame, I'm mad you weren't man enough to fight for this family and instead chose the easy way out with someone almost young enough to be your daughter who thinks you're probably just super.

I'm at a loss, really. I feel saying "no" just lets him off the hook. What does he even want to know what I'm mad about? Not picking up our S this weekend?? Maybe I'll just respond to that, "no, I like spending time with S, a whole weekend of him to myself will be great". Maybe that's all he wants to know if I'm mad about yesterday. I'm probably giving him too much credit anyway in asking what "mad" is.

What do you all think???
