Thanks Adam. I know the trips will be good for me and the girls. A little sad that going on hols with the three of us (or just the three of them) seems to be the 'norm' now. The one on my own is through an adventure group. They organize 'adventures' for people in their 30's and 40's - not a dating thing. More a bucket list adventure thing. I've heard good things. Scary though.
Dilly - you could be correct. I don'tn tell him what I'm doing even though I am not doing anything. For example, I have told him I am going away but have not told him what I am doing. I guess it's part of the "this is my life" and I feel the need to protect it. Maybe it's the same for him. Plus, I have questioned him before, he would go to the gym and be gone for 3-4 hours and when I'd say "How was the gym?", I'd get a huff, followed by a look, followed by an "YOU don't need to ask". That was a long time ago but I've learned to not question when the things he says don't add up.
