Truth is, you get used to it. It takes a little time but living single and alone grows on you.
You chew your food better for lack of dinner conversation and sleep better alone without a chatty someone stealing the covers, cuddling, or wanting something more.
You save money not buying silly flowers or something special for no one special for no special reason and learn to be self-sufficient when sick, make your own soup, and get your own toilet paper.
You stop worrying about dying alone, just dying, and you gradually forget what it used to be like.
The sad but comforting truth is you get used to being single and alone.
It grows on you like an annihilation of might have beens and draws your heart, mind and soul closer to all the good things which actually are.
