Love is only blind for the immature and those lacking relationship experience. The vast majority of us learn that there is an "infatuation phase" at the beginning of new relationships. This is not to be confused with love.
People who subscribe to the "love is blind" belief also believe "you can't help who you fall in love with." In other words we're all helpless.
The truth is each of us (chooses) our own friends, lovers, and spouse. We get to (choose) who we exchange our contact information with, spend time with, kiss, and have sex with. We have to say "yes" quite a few times before we become an item with someone.
It's a little disingenuous to turn around after things fall apart and say; "You can't help who you fall in love with. The heart wants what it wants." This can only happen if one chooses to ignore red flags (hoping) for the best or has a low self-esteem. If you love yourself you are not going to spend much time with toxic people.
(Never separate your mind from your heart when making relationship decisions. The purpose of the mind is to protect the heart.)
"Never love anyone who treats you like you're ordinary."
- Oscar Wilde
