My DP has DC's from his marriage and I have a DC from my last relationship. We have his DC's one day at the weekend overnight due to my DP work schedule he is unable to take them more but we do help out at holidays and when asked.
Anyway I have an issue with the way the older DC acts (I 100% do not blame him as he is a child and I see this being a control issue from his DM) when the eldest DC is here they have their mobile phone in hand waiting on anything that crops up that they can inform their DM. The DC has secret phone calls with her where they report when DP or I tell off one of their siblings (one of my SC has taken a liking to punch, kick and spit at me which I do not tolerate. They also likes to trash the house when he does not get his own way again something myself and DP do not tolerate).
I feel like I am being spied on in my own home. The SC also report when we are in our room i.e. I am watching tv and DP will come in to chat or That DP and I just stand in the kitchen talking (I have always use they kitchen as a 'hang out' area as do my parents etc).
Any advice on how to handle this?
For background DP and I have been together for 3 years lived together for 18months and I was not the reason their marriage broke down.
