Blimey.......you must have lost around 8/9 stones!!!
I wish depression had that effect on me....
It depends what this person wants, really. It could be that he is staying with his partner for the sake of the children. You have obviously "acted" on your feelings. I don't think someone has to sacrifice everything for the sake of trying to rekindle a relationship with someone, simply because this person is the mother of their children. I think he has a lot of thinking to do, and shouldn't see you until he has reached a decision. Then you will know for definite whether this relationship is worth saving. Try to stay away from him, even go away for a while, see your friends, have fun. I wish you all the best, hun! xxx
