Is this being controlling?

[Joiya]

It's a bit presumptuous, but not controlling.

It also sounds like Friend A may be a bit desperate. This is not really a healthy relationship because A is hanging on some guyw ho is not interested. She needs to find some friends and other people who do like her. B is being insensitive to A's feelings... but then again, he was honest about not liking her - so he may be trying to give her the hint to leave him alone by talking about other girls.

Its not really appropriate to ask someone to adjust what they post of twitter and facebook unless the posts are inappropriate, or you are the poster's parent.
