YourWifeAlbedo's question (2)

So a month ago or so I got to know 2 new people online while playing video games and since then we're playing everyday together. So one of them started to write me per WhatsApp and was really nice to me. This is where I started to like him a little more if you know what I mean. One day he asked me to show him a picture of me (only the face) and I had no problem with it so I showed him one. Apparently he thinks that I look really good and wanted more pictures. We started to send each others more and more messages till the point where we write each other everyday nearly every minute. He started so send me pictures of himself after he asked me if I wanted one and asked me if I could send him full body pictures. I did that ofcourse and he seemed to really like it. He gives me literally every day many compliments. So he wants to talk to me every minute and when we're calling each other he doesn't want to hang up because he wants to hear my voice. Last week he told me he really wants to meet me and is sad that I live so far away (though we live in the same country) and told me what he would like to do once we meet lol. When I'm mad he always sais that he loves me too but I'm not sure if that's just sarcasm or not. He said he is very interested in me and gets kinda mad when I'm playing with a boy in my class.
So I know that he likes me but I want to know if it's just in a sexual way or if it's romantic.
Anyone know something?

Btw sorry for my bad english lol

Hello people who are reading this. I'd really like to learn Korean but because this is going to be my first language that I have to learn on my own, I'm not so sure how to do that. I know there are many apps out there which want to help you with learning languages, do they really help? And if yes which do you recommend?
Anyways, I'd be really thankfull if someone can help me out a bit! :)
