How do i cope with a breakup?

i am heartbroken- i really did love this man- he was my best friend- we talked all the time and we never really fought about anything- we have been together for almost 2 years- all of his kids- i am attached too- i dont even want to think about dating someone else- i am afraid my heart cannot take this anymore-i got the old i love you but i am not in love with you anymore. Which to me really means- he is wanting to mess around with someone else- anyways i have to see him tomorrow when i have to go pick up my things- do i say anything to him or just get my stuff and go? I do have some things i do wanna say though- any help i would appreciate itHow do i cope with a breakup?
Wow this is sad. I would say spend time with friends and family. Get things together and recuperate yourself. Go to the gym and let all your frustrations out. It will be good for you. Tomorrow don't say anything to him just wait for him to come back to you. Maybe its just a phase he's going through. Be positive.
