Really difficult to explain but i guess 15 years ago i had a crush on a girl we got on well but she was hung up on someone else and tbh I was an immature dick. Anyway I'm newly single and I'm noticing her on social media she is stunning and coupled with how well we used to get on I'm tempted to get in touch. I dont want to freak her out would i be unreasonable to get in touch or am I just on the rebound?
