How to love yourself?

I've been recovering from a devastating breakup with my ex of 14 years. Long story short she wasn't faithful. 10 months later I'm still struggling to move on. I've been told multiple times that I need to love myself. I have no idea what that means, I dont hate myself. I'm happy with where I'm at in my life, good job, got a house, I'm just depressed from my cheating ex destroying the life I spent over a decade building and having my future plans gone. I wanted to start a family and lost that opportunity so now I feel like I have no direction. How does one love themself and what exactly does that mean?
