My Ex's personal uber.

So I got a call from my best friend and she was asking me for a favor. The favor was.... to pick up her good friend and my Ex boyfriend from the airport. I was annoyed, but she really wanted to drive to Dallas to spend time with her boyfriend and couldn't make it. They have been best friends for years and I became her very close friend weirdly after he cheated on me.   We literally banded together over how dumb he was for messing around on me. 😂 All that aside, me and my Ex don't hang out ever. This is mostly because I blocked him from my life after he took me for a fool and became queen bitch. I completely moved on from the situation but I still don't interact with him or have anything to do with him beside hang out with his best friend who is now my best friend. I fell back hella hard lmao. Like I made a snapchat two years ago and I didn't know he followed me until he snapped me Happy Thanksgiving last year and I blocked him. We dated like three years ago but we still have like chemistry or tension or whatever lol. So I agreed to pick him up or whatevah and drive 30mins to the airport 😪😪😪😪 during the holiday season. The car ride was soooo akwkard because like we were vibing, but I don't know how to interact with him anymore because he's still all flirty and being relationshipy with me. Calling me old nicknames, talking about my family, asking questions, it just made me really tense idk why. I don't think I still love him but I think that I care about him and miss his personality. He suggested to go out to eat afterward and pay for my food and gas for chauffeuring him around. I said yes because um free drinks lol. During dinner he started making me feel like complete shit for shutting him out of my life. He told me he still likes me and I hurt him and stuff. He said that he felt like every time he sneezed I would block him out of spite. I apologized because I understood his point of view I guess🤔. I completely gave up on our relationship and lashed out to punish him by completely shutting him out. BUT I kinda still feel like I made the right decision. He invited me to his birthday party and dropped multiple hints that attending is not optional. He was my first real boyfriend, my first love, my first everything but I just can't deal with him. I feel like I should still just keep him away from me, because life without him is honestly so much easier for me. Especially considering I don't see a future with him at all anymore. I know he's trying to open up a "friendship" window but I want to slam it shut. What do y'all think? Am I just being super bitchy? Have any of your exes tried to pop in to check on y'all? What did y'all do?!
