Avoidant Era???

Who would've thought that little miss can fall for anyone, loves too hard, and sees the best in everyone would turn into...well this. The guy I've been talking to, he's really sweet. And cute and funny. The usual spiel. But we have been...kinda weird recently. Idk if it's just because I'm overly sensitive or I was just moody cuz of my period or wtv but I've just been so out of it w him. Now it isn't just me. I'll talk to my friends about it and they agree that some of the stuff he says and does are just...odd. Which is very much true. But it's gotten to the point where I legit don't even know if he genuinely likes me or or not. He says he does but there are like no actions. I know I should take his actions as an answer but it's hard. And now it's to the point where even the thought of him knowing me more than just surface level scares me. There's so much abt me that he doesn't even know and I'm not sur if I even want him to. I really do hate blaming my current state of self on someone else but I do think my ex does have smth to do with it. None of my other exes have made me feel this way, but after my last one, idk. Trying to talk to people after her is just impossible. She was the only person that actually knew me, even the parts I thought I'd never show anyone. Luckily, I don't have any remaining feelings for her, PHEW! But with the way the relationship went and ended, it lowk scarred me. It feels like there's a wall that's been put up that I didn't even build and I have no clue how to break it down. Despite that, I still can't leave him alone. I know I should for my own sake but I can't. I like talking to him and being around him and listening to him but I just don't know if I can. We aren't tg and I've already hit him with the "do u even like me :(." LMAO !!  I am just incredibly insecure about myself and how others feel about me and if I'm even capable of being cared for the way I care for others. And I don't want that to be a burden on him. I'm still trying to detach but I didn't think it would be so difficult. I'm just gonna crawl into a cave and talk to the crystals and paintings for the rest of my life.
