You never know where you end up. I thought I'd end up alone in a shed in the woods. I am currently married and have two and a half cats (we just met an outdoor cat we're trying to cat distribute our way) and am somehow generally liked by my community despite being unashamedly weird. Life takes you where it wants to take you.

I had an ex do something similar a couple years after we broke up. She was complaining about being alone and asked me if I was happy alone. I am, I love being alone. Got my cat( which I had before her) and my peace and I'm happy. Don't think that's the answer she wanted to hear.

You don’t need to try and convince yourself. It’s true. Loving someone who doesn’t love you back is torture.
