No, although I like my space being alone in the house at night for more than one night makes me anxious.
I moved in with my ex when I was in my early 20s and he worked nights, so I basically lived alone for 7 months, he lived in a tiny village in the middle of nowhere, literally a church a pub and a handful of houses. Electricity regularly died I'm terrified of the dark and we got burgled while I was upstairs wrapping presents.
Been with dp 6 years, lived together 5 now and he goes on week long training courses 2 or 3 times a year, I do a mixture of staying with my parents, his parents or having a friend over as after one night I get panicky and can't sleep.
Although, we've had our son since his last away stay, so I might be ok going forward because it's not just me and the dog at home and I have no choice but to be ok about it.
