Am I overreacting to these strange texts from a coworker?

Like this guy says in the text he’s 38. For context I’m 22. I just started working at this place about 3-4 months ago and we’ve not really talked until recently. We were chatting a bit on our shared break and on the floor, and it seemed like a casual conversation.

We mostly just talked about liking music and games so some similar interests. That’s fine.

I can’t tell if I’m reading too much into the boyfriend comment but no had mentioned anything about that at all before. I am not someone who “gives off signals”.

I’m also really bad at confrontation. I am so anxious to go to work. I don’t want a relationship and I don’t even think hoof this guy as a casual friend. We’ve only talk a few times at all. I don’t make friends quickly, and this situation just makes me super uncomfortable because I have to work with this person and my department has a break room separate from the rest with no cameras, plus we often go to breaks 2-3 at a time so I could end up in this room alone with him and I like can’t physically tell I’m weirded out.

I also just can’t tell if he’s just really bad at sociallizing.

I just don’t want to be close friends. The casual friendly coworkers who sometimes play on the same Minecraft server is all I was interested in and I thought that was clear.
