Oh chick you're not failing!! You're on here talking it through, not hiding away in denial!! You only fail when you completely stop trying!!
Has Mr Lovely got any clue you're trying to lose weight? Maybe nows the time to get him on board to help keep you going? Personally I couldn't think of giving up CD before getting to target because I get too frustrated with slower losses and give up, then inevitably come crawling back to CD again with extra weight to lose.
I think you need to form a plan in your mind so you know where you're going, by this for example I mean say you'll do CD for the days you're not with his Loveliness, and be sensible the days you are with him, have 1200 days when you're with him maybe. That way you're completely in control you plan to increase your cals on those days and cut back on the others that way you're always on plan, stopping you from feeling guilty and feeling like you're failing. It's just a thought.
I know that was waffly I hope you get what I mean!! But one way or another you can do it and I'll always be here for moral support xxx
