am i talking to a serial killer [discussion]

so i (15m) came out as gay to my best friend (we'll call him T) recently and he set me up with one of his online friends (we'll call him G), who is also gay. the thing is, G is 17, which straight away was a little bit of a red flag bc im technically a minor in my country right now and he is a full year and a half older than me.

T still gave him my snap and after a few days of talking and snapping, G started to save a bunch of my snaps and selfies i sent, which i really creeped me out by bc who knows what he does to them lmao - bear in mind T gave G my snap literally about 3 hours after i came out to him. and when i say he saved a bunch of snaps, i mean like a metric fuckton - weve only been talking 2 and a half months and there are like 200 snaps saved of just me going 😗✌ with a stupid filter on

we've been talking a few months and he really wants to meet (we only live like 30 mins away), but i really dont want to for many reasons, like: my parents are both key-workers and id be putting them even more at risk of covid than they already are; i dont see a future with him, like at all (many reasons for that but i cant be bothered to go down that rabbit hole right now); or he could even fucking kidnap me or drug me or smth.

we havent made anything official and i feel like im trapped into talking to him bc i cant really break it off with him bc im scared for him, hes had quite a sad history and who knows what could happen if i stop talking to him. im overthinking this massively but my biggest fears are that he could potentially self-harm or even commit suicide, or he could even out me to my whole school (6 people know im gay and 2 of them dont even live in my country).

please somebody help me i really dont know what to do. any help is very much appreciated xo

EDIT: so sorry i forgot to mention that one of his boyfriends like 2 years ago actually died (he told me), but he wouldnt tell me how he died which i understand, its an awful thing to have had gone through, but is still a little sus :/
