Hi, I'm the blind your talking about and it's not necessarily a about being faithful. I dated this girl within the first month she cheated the second month she cheated. In a span of 2 years she cheat about 20 times with over 30 different people. By the end of it I was more or less going to kill myself because of my mental health.

But I stayed every time. I was totally in love with them. My friend saw her and noticed she was extremely toxic controling me and more or less blaming me for the reason she cheated. I didn't see it. Because all I cared about were hugs and he saying that she loved me. It's been a year or so since then but I still want her even knowing everything. After her best friend told me more or less everything.
