Man here - re-married. First inlaws were alright. Love my current inlaws, absolutely awesome. I completely won the lottery. My parents are nowhere near as good as ILs as my ILs are.
A couple of serious between marriage LTRs: 1) worst nightmare ILS EVER EVER EVER. I used to go to this website:

just to get some much needed laughter and relief. Seriously, they were the worst ever. I totally ducked a bullet when ex-fiance and I broke up.
2nd set - FIL was an alcoholic con man, so he was pleasant to be around, good conversation, but a disaster waiting to happen. MIL was wonderful - better than her daughter.
