Man, loneliness sucks! Best I can say is try and fill your free time as much as possible. I met my wife online, but that landscape has completely changed since we got together! At the time, I was in my late 30s and pretty much only out of my apartment for work or gym. If I hadn’t met her, I’m pretty sure gym time would’ve eventually dwindled to zero. Even if you don’t start a new relationship, you’ll be busy and around others. Better than Netflix being you closest “friend!”
