God I'm sorry this happened. I somewhat understand what you were going through. I dated guys casually where I ignored 100 red flags because I recently came out of an immensely painful breakup or because I felt like they were handsome or intelligent or successful. And to push through all that bullshit and red flags just to have them mistreat you is always heartbreaking but a MUCH NEEDED lesson. If we dont have these lessons, we will always be naive to the intentions of selfish, negative people.
