6 weeks post breakup

it’s been 6 weeks and two days since my breakup and I still cry over him and think about him often. does this make me weak? he was my first and i’m terrified I will never find a feeling like that again. should I be over it by now? how do I speed up this healing process? i’m so tired of thinking about him constantly. I just miss him and his smile, but he didn’t treat me the way I deserve. but what if that’s the best i’ll ever get and I let it go?

sorry if this is jumbled, I just need advice. I want to stop missing him.
