Yep. Boobies and everything....
I can see where the confusion comes in so let me put it another way....
What if he really wanted you to keep it?
You willing to risk that? Are you sure you want to put yourself through the heartache of a conversation like that when you've appeared to have made up your mind completely on the subject?
Acting normal... Well I don't know, I compartmentalise very well so acting normal when things are going t its up has never really been a problem with me. But you'll cope, you really will... It'll be hard but you'll cope. Keep your end goal in mind.
And also, is he really someone you're going to keep in touch with forever and a day? If so, then maybe tell him, I don't know. But then your relationship will be affected forever.
Maybe I'm cold but I would just not be willing to put myself in the situation where I have to justify a decision (if it came to that) or hurt someone when there's no need.
I don't know what to say tiddler, I probably come across as quite unfeeling but I just think that you're going to feel guilty and sh1t about the whole thing anyway so why make yourself feel worse by telling him? It's just something else on the plate that really doesn't need to be there.
