He needs to stand on his own feet, broke or not. Had 2 husbands empty the accounts on me & run up credit card bills with their new lady.
Take a long hard look do you really want to give up your home? If you can afford it don't this is your comfort zone, your critters will always love you you have poured alot of yourself into your home. Redecorate do things the way you wanted but maybe had to compromise about. But sometimes the home place is too hard to continue to live in because of memories, understand that one to.
Take some lessons in something you have always wanted to do be it skydiving,pottery,motorcycles, or just another language.
Learning & expanding yourself takes up brooding time.
Remember some men are just dogs sniffing after the next new thing.
You are a strong person & you have been wounded deeply but with time & friends you will recover & come out the other side a stronger better person.
Momma used to say that which does not kill us will make us stronger.
Oh yeah change the title of this thread like someone else said to I threw out the trash.
He is not worthy of you.
