Of course you want him home, it is normal to want your family together, why shouldn't you, other people have it, why can't we.
As for happy endings, yes you will have one. You will either get back together and be a couple who got over an affair, lots of people do it, or..
my scenario, you will find out things about you you never knew, you will become stronger and wiser and you will find out what you want from life on your own terms. I am glad this happened now, i have taken more risks, met fantastic people, and am on the path to being truly happy with myself.
if you believe one of those two things can happen, then you can start to feel positive again.
As for being a bunny boiler if you want to take it out on an animal please let me give you the no. of
