Feeling a bit insecure

I’ve been hanging out with a guy for around 5 months. We weren’t dating, but we’re not seeing other people, at least I’m not. He’s three years older, an engineer, smart and funny. I’m in college and don’t work, I think I’m witty etc. lately it seems that Ive been the one initiating texts and plans, we used to talk everyday but can it can be a few days before I have to text him again. I asked what his plans were today, he said he’s busy and said we can hang out Saturday. I asked what he wanted to do and he replied “up to you”. I just feel like a burden sometimes. Like I wanna just say “we don’t have to hang out if it feel like an obligation”. I have anxiety and beat myself up a lot and overthink a ton so I don’t know if that’s what’s happening or if I’m onto something. At the same time I don’t feel like I have a right to voice my concerns because we aren’t dating. I like him, he is safe and I like hanging out with him. I just don’t know if it’s all in my head. I don’t know what to do.

If you have advice that’d be extremely appreciated. Thank you for reading.
