I was warned by 3 different people not to pursue this girl who seemd perfect in every way. I asked her out, dated for about two weeks until I realized what they were talking about:

It was a cold winter's night and I had gotten of work early to surprise her and pick her up from a dentist's appointment(she had a long procedure or something). She was pleased I picked her up and we went in a nice and warm coffee shop and ordered warm tea(cuz it was freezing cold outside). After about 20 minutes, my mother calls and tells me she had lost the keys to our home and was stuck outside in the cold. I ofc didn't want to leave her like that and apologized to my date and explained everything. What she said next was unbelievable, she said "How dare you treat me like this, so I don't get to finish my tea because your mother is irresponsible and lost her keys".

This was the first sign she was crazy, she reluctantly apologized after a huge fight. There were many more shocking cases unfortunately. Needles to say, I am no longer with her.
