When someone walks out of your life, let them. There's no use in wasting your time on people that leave you. What you maks of yourself and your future is no longer tied to them. Yeah, you may miss them. But remember that you were not the one to give up.
Nothing is nicer than having someone who. Appreciates you in the smallest things. Accepts you in times of hardships. Comforts you when you are troubled.Loves you no matter what and is simply happy for having you in their life. Love and Friends.
