Maybe you're clingy and annoying(bubbly), basically an extrovert? These are my rules for "friends" on the internet.
- Don't involve or inform me about anything happening in your personal life.
- Don't attempt to small talk with me just for the sake of conversation.
- Do not EVER have an emotional outbreak on me for any reason at all, justifiable or not.
- Don't expect me to care about you or do stuff with you all the time.
Doing any of the 4 things above will annoy me to no end and I will terminate whatever it is you thought we had.
This is not a commitment and it is not a relationship. We are two people enjoying a game/conversation/whatever together, that's it.
Just follow these social rules and you'll have a healthy long-lasting partnership with someone on the internet. Simple, isn't it?
