Ex Problems...Help?

So my ex and I broke up in April. We only dated 2 weeks. We never really hung out...just texted all the time. The breakup was kinda hard. I still feel weird talking to him.
So here's my problem. He wants to hang out. I keep telling him I feel akward even talking to him yet, and he still insists we hang out. How do I nicely just tell him no?

Thanks.

^^ I agree.

Sometimes being nice isn't an option so you just have to go up to him and tell him! He obviously doesn't care how you feel. You've already told him that you feel arkward just talking to him, and he still doesn't get it. You gotta tell him directly. Good luck.

Thanks.
I just told him I simply don't have time to hang out, I still feel weird talking to him, and Im just not ready.

All he said was okay, but if you ever want to hang out let me know.

But thanks you two for your advice. :)
