Do it face to face, without any extra malice but be truthful. To be honest, that's how I suggest you do all your break-ups.

Time heals all wounds just try to focus on yourself and no one else accept you. Delete and block his number and block him on social media as well so you are not tempted to view his page. Go out and have fun with your friends. Keep yourself busy and pick up a new hobby. Getting over your first love is hard, I understand I've been there but I have healed.
