Great to hear from you, rose.
Whenever I was about to "walk into the dragon's mouth" (i.e. head into a situation with heavy alcoholic stress) I always found it helpful to play the tapes in my head beforehand, so I wouldn't be surprised when things went awry.
Will you be able to take the car and go wherever you wish, or will he give you flak about it?
If things get bad (abusive) do you have a way to get home?
What if he asks for more money and you say no? How will you handle his anger?
If you're kept awake, pestered, or belittled for wanting to have your own experiences there, what might you do to get through it?
None of these things may happen (hoping,praying) But if they do, you might find that thinking through an "escape route" beforehand makes it less stressful than it would be otherwise. Half the shock is when we don't see it coming.
I hope you have a wonderful time and treat yourself well.
Hugs,
