Thanks Nicole, I'm sorry you're going through this too. It's the hardest thing I've ever faced.
Thanks for your words Joseph. I am trying to let go but finding it difficult, I think it's due to not really understanding why this is happening, I flit between thinking it's just a loss of love, OM or a midlife crisis. I've realised my W cannot sit in the house alone when she has the kids, she has her friend round on an evening and she is not showing the kids much attention, they're calling me in bed late at night saying Mummy has let us go on our phones, we've never let them do this so late. I guess the not knowing is making it difficult.
I get my new house this weekend, so that's going to give me something to focus on. My plan is to begin giving her lots of space and only contact for the kids while GAL. my biggest worry right now is that as this moves forward I'm going to see her going out and maybe with other guys, not sure I'll be able to deal with that!
