I fell in love at first sight in high school and now it's ruined my concept of love.
What about this relationship ruined your concept of love?
Well, I fell in love so often and no one ever stuck around.
People in high school are still kids and they are immature. They do not have the experience necessary to realize what entails an adult relationship and love life. If you are still affected by your thoughts of love experienced in high school, you may need the the help of a therapist to move past those issues.
I can't help it. It bothers me a fuck ton.
Keep exploring your romantic side and don't give up on love. One day you will find who you are meant to be with and the two of you will be happily together for a long time. It's all about patience and perseverance.
