Been talking to a guy i can't tell people about

We met online late December. I haven't seen what he looks like, but we're talking about meeting maybe next week (in public duh). We text all day and talk on the phone pretty often, and he's a really amazing person. Cares about me, open minded, checks in to see how I'm doing. Maybe its toxic of me but he worries about me and, yea I always make sure he knows I'm okay and whatever, but it feels kind of nice to feel so cared about?

Anyway. Hes a really amazing person with a big ol heart but there's... quite an age gap between us. I'm terrified to tell me friends and the like about him- I'm not ready for the judgment. And I feel shitty cause thats not fair to him either
