Hey Op....get a life....best advice for right now. Get yourself straightened up and get ready to be back in the gene pool! Start exercising to feel good...start dressing to impress from now on. Don't reply to any calls from STBX until a fwe days afterwards...remember...you're busy getting on with your life now....don't be hanging by the phone for a call from him....that is what he wanting.
Leave MIL alone....just call to say hi and that's it....unless SHE invites for something....
Take care....and don't drink on a empty stomach!!!!
