Should I tell him?

I’m still in love with my ex boyfriend. I know for a fact however that he’s not in love with me. For months now, I’ve been dying to tell him exactly how I feel. But what’s stopping me is knowing that telling him won’t make a difference. If anything, it will push him away more. He doesn’t go for the long love conversations and I know it won’t make him love me again. But my friend told me I should tell him. When I told her no, I gave her my reasons and she left me alone. She texted him after and said “I think you and ashley need to talk. She has a lot to tell you.” And now he won’t stop begging me to tell him. He doesn’t know what I’ve been dying to tell him, and I was planning on keeping it that way. He probably thinks it’s something silly, something that’s not that important. I want to tell him so bad, but I’m scared. And I know it will only hurt me more when he says “I’m sorry. I don’t love you anymore.” or “Ok” or “Wow” like he always does. Then I’ll say “Yeah, I’m sorry.” and he’ll say “Don’t be” and I’ll be like “Well I am” and he’ll say “Ok.” and then we won’t text each other for another few days, or week, or month, or forever. I just don’t know what to do. Should I tell him?
