I’m 46. I had some really bad breakups in my life, was alone for a couple of years. Until I met my (now) wife just 4 years ago. This changed everything because it made me realize that what I thought to be love before was just a shadow of what love truly is.
Keep looking forward and do not torture yourself over what could have been or what went wrong. Nothing went wrong. It’s just life that happened. There will be some amazing person out there and you just haven’t stumbled upon this person yet.
It’s ok to grief a bit. That’s healthy. But look forward and do not hurt yourself in the process.
