I don't have any children Valhalla but I have been involved with DP's kids since the youngest was about two years.
DP, his ex wife, her boyfriend and I all have an excellent relationship.
I am scared of many things re DP's illness, the scariest being that I will be in charge of his PFB, DP would also prefer if I was in charge of DSS2 as well.
I did let loose a couple of weeks ago and DSS1 heard my feelings on him nicking my cigs from my underwear drawer and probably learnt some new words , even though I am irrelevant as I am not a smack-head.
I have no idea how much DP will let me take charge, I have tried and tried to stamp on the smaller misbehaviours (at DP's request) but then had no follow through support.
DP is the one going out in his car to search for his son while I search DSS room and find allsorts. DSS gets grounded for a week which ends up being a good time for his dad to find him a better phone contract.
DP is sending the same mixed messages as XW was, if I am in charge, I will be in charge, and I will have help, maybe not being quite so close will help me be firmer.
