I was supposed to be staying at Dm's for a few days, to relax as I've been a bit down.
The whole time I was there her husband really seemed to resent mine & my 3yo's presence.
Mainly being overly strict with my ds. He was constantly on his case 
For example, Ds had Toy Story on & Sd wanted the Grand Prix on. Sd mentioned this in passing. When he sat down he just sat there looking angry for a minute & then started shouting, stormed out & slammed the door. Came from nowhere
. So the rest of the day felt really oppressive every time he came into the room.
Later on when we were eating a roast my Dm cooked, he was really bossy at the table, ended up putting Ds off his food. Sd snatched his plate away & put it all on his. Shouting, what's the point in giving my ds food he won't eat.
At this point I'd had enough. Lost my rag, pointed out that Ds is my child & responsibility. I asked Dm to take us home & that I'm never bringing Ds back to be treated like this!
