"LET" ? What the devil is that crap? I advise her of the situation, and she is to do likewise. I prefer to spend time with her, but if I want to do something or buy something, I do it. If my plans conflict with something important of hers, I will try my best to accommodated her. She is not stupid about stuff. Otherwise, I would not be with her.
She is my best buddy. I want to help my buddy as much as possible. And, that is a two way street.
I have asked her about which guns to buy when I can't make my mind up. That is a really bad idea. She will say, "Those are nice. Get them both/all. You have the money. You deserve it." Some help she is... LOL!
I take trips, sometimes by myself. Time doesn't matter, other than we will miss each other. I took off for 10 days for my bull elk trip this past fall.
Gosh, I do love that woman.
