What lesson learned

I had a bad toxic break up over a relationship that I was in for 4 years .
A year and half of suicidal thoughts and a mental breakdown in the middle of that . I lost 3 stone in 6 months .
Never cheated on her . Never cheated on no one in my life . I had offers when I was with her with a few other women .
Said No I can’t .
The lesson I learned LOVE .
You always go back to that or else you be bitter for the rest of your lifetime.
What she thought me ?
Never get dependent on no one for your happiness. It’s easy for me to say that now but when your in a relationship it’s a different story altogether .
Love Dependency is a very thin line and my experience with it is that you have no control over it .
I’m single 14 years and I read a book called Co Dependant no more a great book by Melody Beattie and I related to a lot of it and I’m single 14 years .
The moral of the story is that the whole world is connected and what changes that is peoples beliefs .
