The alien strikes again!!! Looks like you've got a handle on it, so that's good. Right now, I think the questions would be the following: Is it good for our children? Can I handle it if we're divorced?
A vaction can be had with an alien. I did it after our second reconciliation failed - we had cruise tickets already paid for, and we went. Was a little difficult, but I went in with no expectations from her, and I knew ahead of time about her new boyfriend, so I coped and focused on enjoying myself.
In order to pull that off, you have to achieve detachment, and I don't know that you're quite there yet. So, making tentative plans would be ok, but I wouldn't put any money down.
As for the Texas weather - about time we got out of summer. At least for a little while. Does this warm streak mean another summer of 115? I really hope not.
