I broke up with my ex about 4.5 months ago but I still really like him and I thinks he still likes me to. We are hanging out tomorrow. What should I do? Should I tell him?

You should leave him alone.

I thought you broke up with HIM? Hm?

No, don't make that 'mistake'. :rolleyes: What if (JUST "what if") you're wrong and he doesn't like you as much as you think he does?

Hang out with him, try to see how he really (still) feels about you. If you see he might (still) be interested, drop some hints you are interested, too.

This is my opinion.
