Met guy on dating app

Certain things don’t add up & we’ve been talking for 2 weeks , I’m bad at rejection and confrontation but I didn’t wanna ghost. I did at one point

He sent me this one morning , this kinda freaked me out. No good morning nothing

I tried to ignore but got texts every 3-6 hours about random shit I don’t care about.

Now I’m faced with this.

I hate rejection & I hate being overly mean.

What do I say so he leaves me alone?
