I'm really sorry to hear about your relationship hun but it sounds like you've been doing really well despite that and there will always be support for you here if you need to keep the motivation going but I would suggest relaxing a little over the need to weigh yourself everyday and remember that any loss is a loss and a step towards your goal, which even if you get there a bit slower, maybe that will mean you find it easier to stay there.
I really hope that your relationship either changes for you hun, or that you gain the strength to leave, you deserve to feel loved and respected, a few years ago I felt how you do now, my ex really didn't love or respect me any more, my family has always been dysfunctional, we''ll say, and my self worth was at an all time low, my partner now loves me totally and while we have definately had our problems I've come to realise that being on my own was better than being with someone who made me feel like I was worthless, because your not, no one is, everyone has something of worth to bring to the table.
You sound like an intelligent and lovely person and this is what you need to remember, :grouphugg:sending you hugs, and lots of luck for your next WI day, but keep off the scales til then. xxx
