Heartbroken & Hopeless

My boyfriend recently broke up with me. After feeling like something was wrong and him becoming distant he said we should just be friends because he has a lot going on. I don’t want to seem inconsiderate but I’m questioning if that’s really the reason. He said something similar last year when we broke up (but we never stopped seeing each other). I thought I was ok, but yesterday and today have been hard. I can’t stop thinking about him. I’m starting to feel like I wasn’t enough. I’ve gotten into the bad habit of comparing myself to girls I think he’d find more attractive. I feel stupid for crying and being upset about it but I can’t help it. I’m really trying my best to move forward but I’m having a hard time right now. I don’t know what to do.
