I got divorced about 4 years ago and spent the next year on my own in counseling. I thought it would be good for me to reflect on what went wrong and why I didn't see it coming.

Came to the hard realization that I was painfully co-dependent and didn't really have my own hobbies or interests. With my ex, everything was about "us" and nothing was about "me." Your significant other should absolutely be a high priority, but it's also important to have your own interests and alone time. People are individuals and a good relationship will grow with them, not over them.

As my counselor put it "If I can't love myself, why would I expect someone else to?"
