Ok. So tell me how could have handled this better. A little back story first
My neighbor wanted me to come up to the lake tonight
I decided to go no matter what on Friday as that's part of my GAL
Anyways, I told wife that yesterday and she was upset. I told her you are more than welcome to come. She said no because neighbors wife wasn't going. She then asked about S. I said well if you aren't going is rather him not come so that I can just have a day to relax. She wasn't pleased about it but didn't argue either
Fast forward to this morning.
S asked me when I was going to be home. I told him I was staying with neighbor tonight. He said I wanna stay there, I just wanna be with you
So to avoid any confusing I told him I was going to lake and told him it was daddies only not mommies and sons
Fast forward to tonight I FaceTime son and he sees my neighbors son who is 13
My son is 6
Wife hangs up
Then the following text. This is were I'm wondering how I handled it and could have done better

M: "He knows we are at the lake"
M: "why did you hang up?"
W: "I can't believe you. You packed a bag and snuck out this morning so he wouldn't know then waited until I had to deal with him to let him know. So you can call him and explain to him you are a selfish jerk and didn't want to have to deal with him up there"
M: Omg!
Really! You weren't there this morning when I told him I was going to lake
I told him the truth
Because he thought something else
He was even saying show me the lake while i was talking to him"
M: "I didn't mean for you to have to deal with this
Which is why I told him this morning "
W: "No you told him he couldn't go bc I didn't go. You put it on me. He told me that. And whatever. He didn't know will was there"
W: "I just had to deal with him sobbing to me bc will was there"
M: "I did not tell him that
I would not do that!
I told him daddy was spending daddy time with Mr. David
He then said, "I want to stay with Mr David tonight too. I just want to be with you"
I told him no we were going to lake and that mommies weren't going. Just daddy night
He then said I haven't been to lake in 12 years and I said tonight was just daddies and that he would go plenty his summer including in a couple weeks
He was completely fine"


Anyways. I'm curious about what y'all think how I handled the texts
The 180 I pulled is I would normally get heated and get really mad
But after the last text I sent I let it go
I'm just really pissed because a few weeks ago she goes to a music festival and I watch our son the whole weekend
But I go for one night and want to enjoy the night and day and I'm a selfish jerk
I set a boundary with her on Friday and now I'm hearing shot for being terrible
Go figure
