Thanks for your advice and comments so far.
I did decide to meet up with my friend yesterday and we went to an art gallery together and afterwards, for drinks. I think we both wanted to see whether we really could manage a platonic friendship again. Well, everything started well, mostly small talk. As the evening progressed, however, I could feel us getting closer and closer. It is strangely comforting to be around someone you can truly be completely yourself with. And I find his company so easy.
Towards the end of the evening, I could feel an obvious tension between us, it was almost glittering. Before we parted company, he said he was still in love with me and that's when he made a pass.
I suppose I now know we cannot be simply friends.
Little Red, your situation does sound very much like mine. I'm not sure how to pm though - do I need more posts for this? As regards my marriage, I do love my husband as a friend and companion. I cannot describe him in less than glowing terms because he's very good and kind to me. The main problem we have is that we are now more like friends than husband and wife. Sexually, we have very different drives. His sex drive is very low which I find difficult to deal with. Currently we have sex about once every two/three months. I have broached my unhappiness with this but what can you do? He has a low sex drive, mine is high and this won't change no matter how many times I talk about it.
Little Red - what is your marriage like?
