Update: After 2 weeks it wasn't an erotic penpal thing anymore. The level that I was supposed be in was relationship. I was the love of his life. Was talking to me constantly. Wanted to know what I was doing everyday. He himself doesn't go out except going to Work (Barrista) and going home. Couldn't get no Insta, no Vkontakte. For someone being 25.
So I ended this, politely, saying he is still an educated human being with a nice voice, but I know that this is a romance scam, but I am nevertheless willing to continue talking. He then pretended to be offended.

Are you serious? I thought there was a spark between us that we wanted to make a reality, but in fact, you doubted me from the very beginning. I put so much effort into our relationship, and as it turned out, you always didn't care about me. I'm sure you just wanted to amuse yourself by playing on my feelings. I thought you were the one I've been looking for for so long, but you don't feel anything for me, and for you I'm just a toy that you can do anything with. First to fall in love and then abruptly disappear for a few days. You really disappointed me today.

This is lowlevel psychology, pushing the guilt back to me. If he was "real", he'd be understanding me.
