Falling out of love

My boyfriend treats me like trash... I know it’s stupid to continue to be with him. We’ve heavily fallen out of love...

But he’s my first in everything— sex, kisses, love, dates. I’m... crying as I write this... But I feel he doesn’t love me anymore.

What do I do? I love him. Even though I always feel miserable around him. And even though I feel relieved thinking of breaking things off with him... :’( Please help.
