Am I wrong?

A young man messaged me on tiktok one day, it first started off with his comments on my post and then he messaged, I thought he was an aqauntence I knew and even asked but turned out he wasn't. After that I thought the conversation would end, cool BYE! 👋

But he continued to message and I don't want to be rude and I hate seeing unread messages on my phone. If he would say anything inappropriate or bad I would have blocked immediately but he didn't.  

Anyway fast forward, so a little back story about me, I am single and have been single for 4 years now, I flirt with other single people because we are single right, lol we can flirt with whoever we want if they single too of course. But we all know this general knowledge that if we don't get attached to someone and if the other person gets a girlfriend/boyfriend PERIOD, I will cheer you on friend 👏. There's no bad blood between us, we weren't dating and I don't have a right ti be angry RIGHT. This is general knowledge!

Back to the story a few months went by, and we have been talking on IG, now here's where some people will judge me a little but I don't care. 1. I was aware of his age (he dates older ladies anyway so to him it didn't matter) 2. I flirted with him but I did put boundaries 3. I have told him countless times that I am not interested in dating him but he still persist and still doesn't respect my boundaries.  I thought that we had an understanding and I still thought that after a while he gon get bored and then I can just delete his number and go back to my normal life. 🙄

This DUDE literally told me all his problems, basically making me feel bad that if I stop talking to him then he won't survive anymore. Firstly no I did not let him manipulate me, let me describe him, his very slow, hasn't experienced basically anything, super super sensitive, living situation not the best. And I told him that he shouldn't be telling me these things as if his relying on me to be there for him, Secondly I've told him many times that I am not his mother and I'm not a teacher, the way he acts is as if (wow this older Women is so wise, tell me how to live life) like WTH.

Anyway so I'm leaving the country in a few weeks, I'm getting a new number and everything and I was going to just delete his number but he made me feel so bad, I kept thinking awww but he doesn't have any friends and his told me before that he appreciates my company and advice or oh no but his going through some really bad things at home, he already lost his father and his mom is sick now too, I can't just leave him like that. I helped him to prepare himself for me disappearing one day too but he still..... Ahhhhhh.

But I have decided to cut it off, I wasn't supposed to be talking to this boy anyway, I shouldn't have entertained it. I want to live a peaceful life and his just giving me stress, it's not my responsibility to make him feel better, not once have I told him any of my problems but he told me his whole life story. I also don't buy that story of him saying his slow, at your big age you should know general knowledge bruh, his literally manipulating me to feel bad for not liking him and if I find someone he will be sad and has to deal with his problems alone.

So am I wrong for blocking him?
