We don't have a pact exactly, but we're both into keeping healthy and sane so exercise features large (added to this we both love our food and with my thyroid/metabolic issues i would turn into a sofa if i stopped exercising, though he seems to be luckier in that regard!).

I actually wouldn't mind very much if DP looked a lot different but i HATE seeing him low/down/sluggish so i am very keen that he gets the exercise he needs. I know he fancies me like mad and he felt that way when i was 101kg and 77kg so it doesn't matter too much, but he also knows that at 101kg i was unhappy with my body and not as confident or healthy as i naturally am when i have a normal BMI. He is my best friend and is really honest with me, so if i say "am i gaining weight?" and i am, he says "yes". I'm not offended by honesty though so maybe not the best to advise.

I would ask if she can keep Jaz while you go to the gym for 2 hours and when she argues you tell her to come with you for a walk instead.
