Is my best friend fake?

We were supposed to hang out at the mall today and had planned ahead, my mom was going to pick them up then drop us off at the mall but I needed their address and kept asking for it but they kept making excuses saying they need to check their mail to see their address. Which would be fine but they never sent their address which seems dumb to me cause if they wanted to really hang out with me I feel like they wouldn’t have forgot.

I feel really hurt cause I consider this person my bestfriend but ig. I’ve been catching weird feelings for a while, they almost always bring my intelligence/looks down by calling me dumb or insulting my appearance in one way or another. They usually do this in a joking way but a lot of the time their jokes go too far and can actually just hurt. Usually when I talk to this person they just haven’t been making me feel great lately.
