cw/tw: mentions of grooming and Idealization 

a few weeks ago I met someone that seemed very kind and cool. they managed to help me calm down during a really stressful moment that was nearing me to a mental breakdown and we started a connection. 

they made a flirty remark as we talked about our interests, stuff escalated from there and eventually they wanted to see nsfw pictures of me. I never sent them anything, and they were willing to send stuff theirselves. 

They coincidentally fit my ideal type of person, so I spent a lot of time daydreaming of what they did offline or how they spent their days. They sent me a face reveal and my idealization was shattered, I never expressed my disappointment but I was getting ready to leave them. They're really older than me.

I'm still talking to them because everything about them is perfect despite their appearance (I know this sounds really critical), they make me feel really good and safe despite the obviously dangerous situation, and they seem to actually support me. 

I've become so obsessed that I've been neglecting my homework assignments, eating, sleeping or even doing any of my hobbies. 

I find that the more I'm honest with them, the more I get entangled with them. I also keep seeing angel numbers that are related to romance and positivity when I think of them, so I keep thinking this is fated or some sort.

Im having difficulty because I was just choosing to just grey stone (not really being honest to them and being unemotional) them and then leave, but i keep falling back into wanting to be theirs. I just think I'll regret "being the bigger person"?

they know a lot about my situation and how I am at this point, they know I'm pretty vulnerable so they're aware they can be a big help to me. 

I just feel like regressing and being with them, but my friends advised me to leave. 

What should I do?

if you read this entire thing, thanks.
