It's hard to see what's best for yourself when you're invested in a relationship. It's not always easy to remember who you are and what you want.
You can start to lose yourself and forget to make yourself and your happiness a priority.
There is a lot of sh*t we put up with because the pain certain relationships bring us is less intimidating than the pain of letting go of the person you love.
There's nothing wrong with admitting a relationship has run its course.
Even if you can't conceptualize your life without that person, with time and distance, you'll be able to see the relationship for what it was: toxic as hell.
