Hi Everyone,
Here is the link to my old thread:
www.mumsnet.com/Talk/relationships/a2419130-Recent-transgression-old-infidelity?msgid=55425361#55425361
So I am 3 weeks into my separation, and the main reason why I am posting is because I feel intense sadness when I wake up in the morning and at night.
If I am being perfectly honest, I know that I have made the right decision to separate from my husband, and I am also enjoying thinking about just myself and my children. I enjoy not having to worry about what my H is doing, has been doing, etc. I enjoy making decisions for the sole purpose of pleasing me and my children.
However, I do not enjoy the extreme sadness that I feel when I think that my relationship is really and truly over. For me, I know that it is over. However, H is still not accepting of this. He is still in the process of "trying to change". He does not really accept that we are separated, he is constantly searching for some sort of reassurance from me that there is a chance that we may get back together soon, I think he actually really believes that this is temporary and that I will change my mind and say "ok, Im ready to have you back!" I no longer have the energy to keep repeating "I don't want to be with you, I don't want to be with you, we are done, we are over" etc etc etc
I do love him, I really do, but that does not mean that I want to be with him. I have absolutely no desire to show him any affection or to get any from him in any way. This is how I know that it is over. I do not worry about him meeting anyone, or shagging anyone or anything. I just feel so sad and down that the life I thought I had and was continuing to build on is not to be anymore.
I do have very supportive friends and my family are also being supportive, but I feel like at times I have no one to talk to. No one in my life understands the sadness that I feel everyday. I don't just have down days, everyday I am down at some point or the other. I need a break, I need to just run away from it all but I can't. I want a holiday, but I have no one to go with. I would go by myself but I worry if this may only make me sadder once away. But I really do want to go and lie on a beach for a couple of days with a good book, some wine, and get a break from my beautiful children 
I don't know why I am posting, maybe because I just need to let this out and feel I can't in real life. I hate crying. I feel like it is difficult to move on, as everyone that I have told that it is over responds with "oh you will fix it, you will get it back on track" blah blah blah. I suppose that what I want is for my heart to catch up with my head, and then I can get on with life and leaving this sadness behind.
