I hate the reactions to these posts
Why do you hate the reactions?
I hate it when people talk about me behind my back
People are going to react to posts however they see fit in a public forum.  It's pretty self-centered to think that they should react a certain way, or that they are only talking about you.  There are lots of people and topics for them to be discussing.
No I think they are all talking about me. They are all jealous of me.
They could be jealous but they are allowed to react how they want to posts as long as it does not violate the rules of the forum. When you put yourself out there, people will react to what you put out and you shouldn't expect people to all act a certain way because you want them to.
