Me and my partner have been very unhappy for a while now. I am a solo parent anyway it seems, my children are 6 and 3 and are the most wonderful little people, I want to end this relationship (I am financially independent) and would stay in the house I am in. The only thing holding me back is the affect on the kids, I have tried to stay miserable but I can’t. I am also fantasising about other men so I know I need to get out. What if I ruin their lives?
