Dear Tim

I am sorry that your relationship came to an end. You appear to have learnt a lot and have take good steps to improve your physical & mental wellbeing.

I guess you keep on looking after yourself for yourself and not with the goal of getting the lady back & I hope she is doing the same. Maybe you could wait until Christmas before you approach her by sending her a card maybe thanking her for the good things that she brings to this world & wishing her well for the future.  She may of course reach out to you in the meantime.
