Hi Danny,
When I read your story, it's like I'm reading myself.
I know how it feels to be away from the one you love because of work. It was a problem between my ex and me. I was angry when he got to go somewhere without me like seeing friends or skiing, for example, because I knew he was going to leave soon for few days or a week. I felt like I was not a priority either and I was not interested to do what I used to do when I was not with him... Why ? Because I was focusing on spending time with him and left myself behind...
Unfortunately, I realized some things after the break up. We often focus on problems instead of solutions. You told her how you feel about this lack of proximity, right ?
You should take care of yourself when you're not with her. Doing what you like.
You can try to count the moment you spend with her and enjoy that moments instead of counting the time you two are apart. You missed so much when you think about the negative. Don't make it an issue like I did. You don't want her to feel guilty to work. This is her job. Also, ask yourself : Do you prefer not having her at all ? Of course not. Between having her for a day or not at all, the choice is easy.
But you can tell her that you want to spend more time with her. That's totally normal. Unfortunately, if you ever feel unhappy, then I think you'll have to think about what you want and what you deserve for yourself.
I wish you all the best, Danny.
Take care of you
