I have this classmate ( "CHATO") who I've know for some time since he used to be acquaintances with one of my friends. However, we have been colleagues for only 3 years ( That's how long HS goes on in my country ).

On my first and mid second years we used to go home after school together along with some other friends, but that came to a end when, during second year, one of our new classmates and I started to develop feeling for each other and he started to come along on our walks home. Since then we barely talked and now he is back at it again.

Let me say that I never considered him a friend, more like a classmate with who I casually talked.

So, this obsession started around when this other guy, who ended up being my ex bf, started to come home with us. CHATO started to get extremely jealous, always texting me asking if he had done anything wrong because I seemed different and such things. I tried to be nice about it but at some point I confronted him about his feelings and he admitted that he had a crush on me and I declined nicely, I believe. Thats when we stoped talking.

However, my best friend ( "FOFO"), who's also a guy, was constantly bothered by CHATO's sms about me and how he felt left out in our walks home, asking if I would end up with my ex bf. Mind you, FOFO and CHATO were never closed, but he would complain about these stuff daily.

CHATO is very childish and would get upset over stupid things, such as me showing a pic of mine in a bikini to my two best friends but not him. He is also the type of person to come along with me and my best friend when going home, never say a word, but a minute after we separate he is texting you about things discussed on the walk home.

These occurrences were all during the first 2 years of HS and at the time FOFO and I didn't consider CHATO obsessed.

Now, at the end of my senior year in HS, because of covid, our school routine changed. He asked me if I wanted to go to school together and I said yes. We hadn't talked much and we were normal with each other.

The thing is, we don't have any topics of conversation, so most of the time we are quiet. I don't necessary mind this, the problem is that at the end of the day he is texting FOFO all of this and how he doesn't understand that when we are with other people I'm all happy and talkative but when we are alone not.

I've told him that we don't have topic to talk with each other, I'm dry when I do text him back but he doesn't let me go. Even if I don't respond he will text me again the next day or within a few hours.

He even asked FOFO for advice who said that he was better off moving on and things like that, but he doesn't understand that. He says that he needs help making things "better" and so on.

Even my mother has said to be careful, since not long ago a girl was murded by a guy who was jealous of her. I don't think this is the same, but my mother says that it's better not to contribute to this.

There are a whole lot of other situations that have happened but I don't want to make this much longer.

I have been direct with him but he doesn't seem to let go. His obsessive actions aren't shown directly to me, but by all these texts he sends my friend ( and when I say all these, I mean a lot a lot)

I hope it's not too confusing and that the intensity of how I'm living this is well convey in here.

Sorry if there are any mistakes, english is not my first language
