OK,
just got a text from XH:

Hello. Are we going to split for the phone for (son)?

It is son's b-day this weekend. He wants a new cell phone, one that costs more than what we would normally spend on a b-day. It is definately not something that just one of us would give him (while the other bought other gifts).

Distance for me does not include joint gifts. I am tired of portraying this happy family that we are not.

My instinct is to just tell him that we can each give son half of the money in our own cards so that he can buy the phone himself.

BUT,
since my instincts, much like those of George Costanza's, are usually wrong...my plan is now to run things through here before I act. It seems that sometimes I seem really bitchy when it is not my intent. And, I tend to overexplain in my answers.

SO? Any input? It is a mundane thing, but I have learned my lesson to think before acting.
