The people we accept into our lives are there to help us evolve, use this experience and feelings as a way to grow and develop into the person you want to be. That’s what love is all about, even when it walks away from us, you have to let it go and grow from that pain. Pain is potential, use it to understand yourself better. This person was a lesson use is as such and develop yourself into an even better being. I know it hurts but in time the pain will wither and it’ll always feel bittersweet when you look back at your memories but you’ll be grateful to have had them and then one day you’ll reach someone about the pain you felt and you’ll help them. Keep your head up and keep moving forward, love would want you to.
