I don’t think it’s a great idea to live with her if you’re not going to be working and she is. You’re going to be waiting for her 24/7, in a place where you have no connections, no work and don’t speak the language; whereas she is in her regular element and needs time to want you, needs time to attend to her job, friends, family, life. The magic could turn into an obligation for her quickly.
I think you can either a) Go whole hog and find a job in paris somehow or b) be with her on weekends but for the most part, travel to other places in europe/france during the week at least some of the time so you aren’t suffocating each other.
Alternatively- Is it possible to find an airbnb or such, for a month to start, in a place that is far enough to be affordable but where you can still take a train to go on dates a few times a week?? And then make the assessment of whether you’re ready to cohabitate.
Also, what does SHE want? How does she feel about you moving there? you didn’t mention this anywhere in your post 🤔
"After lots of thought, I’ve made the difficult decision that I am not coming home for holidays this year. For a lot of reasons, it simply isn’t in the cards this time . I feel badly for the disappointing news, but hopefully this is enough notice that I am not included in a gift exchange or other plans. I look forward to video chatting with everyone at a time that is convenient for all of you together. "
