As has been said before, this topic is done on a regular basis and there will never be a common ground.

There will be those, like me who believes that it is right to share this aspect of my life because it has an impact on our life together.

There will be those, who like the OP believes that is is not a topic worth discussing with their SO.

OK so who is right, well no-one and everyone, we all do things which we feel is right for our own situation. So why not call a truce, stop the war and all live in peace, Oh Damn, I forgot we are the human race, we all want to be in the right, we all want to make sure our own opinion is the one that is shouted the loudest.

On a final note, at least for now, get over it and move on.
