Am I dumb to..?

I need a few opinion here, I think I still like someone I dated on here once, she was my first gf, and well I think I still like her even though she hurt me, and I have not talked to her in a while, I just started thinking about her. Does anyone remember Sierra Lynn? If so that was my gf, I think her username on ep was 1995lynn(don't judge me please we broke up 3 years ago). I care about her still, and I would talk to her again, even though she hurt me because she had been through a lot. Am I dumb for still caring?
