She's going ahead with the house. She can afford it alone and getting out of their previously shared space will be good for her.
Good to hear another solo camper on the boards. I car camp in remote places, dayhike, and backpack solo often. Once went three days without seeing another person. I didn't think about it until you said it but, I can go hours and days without a word spoken. I's like giving yourself up to the natural world. What's that word? Inundation? Totally immersed in your surroundings. Bliss.
