I can promise if I put up a post saying my fella wouldn't allow me to speak to someone. There would be all kinds of remarks about control and abuse.(I never suggested you golden,was I was merely taking the other perspective.)
He spoke to her online. They didn't go for coffee.
Or Fk.
And no guys don't get the frenemy thing. Cos they either like someone and hang with them. Or they don't, and don't.

They don't play all this social politics b.s.
This is why I, as a rule, don't get involved with women as friends.
If she didn't want him to speak to her all she can reasonably do is ASK him not to, and explain why. That's it, that's all you get.

No one has the right to command who I speak to, or you speak to.
And social "games" gets old real quick.
That's how the real world works, and its something you realise as you get older. If someone is going to be unfaithful no amount of restrictions will stop them.And if you don't like how someone acts around you don't hang with th and pretend to be friends.
I guess I just take a straight forward approach to things. I find it makes life a lot less complicated.
