How to get my mind off of him?

So it's only been a few days since we broke up but I thought he'd want to work it out and call or text me but he hasn't. I know he was going to be busy this week but no one's ever that busy. Guess I wasn't important enough to him. Can't believe I humiliated myself by going to his house when we broke up. I have some of his clothes in my house which he probably doesn't want cause he hasn't even contacted me for that or anything for that matter. Again it's only been a few days but I just feel so heartbroken because I thought I mattered to him. I don't want to contact him because I already humiliated myself.

What can I do to get my mind off of him? Is it possible he'll miss me and end up contacting me? Or should I give up hope?

I feel like a loser for being a loyal girl who loves hard. 😭
