Mark - this:-

"I can control a situation under normal circumstances. It is when my wife turns up ready for an evening I find the hardest, especially when she is making so much effort for somebody else."

Yes - yes, yes!!! I can relate to this!

There have been times when my W has come to mine to pick up my S7 when, well, lets say it her G-string has been quite obvious...Grrrrr....

But hey -what are you going to be able to do about it???

Thing is -you need to DETACH DETACH DETACH ...

I appreciate that is easier said than done...but the effort you put into this at the moment will have results...if not in terms of your R - but def in terms of your well-being....

And in view of your sitch at the moment - that is going to be a good thing...

Regards- Simon
