My partner has an older son who is 14 from his previous relationship. I have known him for 5 years.
They moved in with me about 2 years into the relationship.
Since he has got to the teenager years DP just seems to be unable to effectively parent at all and it's just a horrible environment. If I'm honest I can't stand him (his son), he's rude, disrespectful, never does anything you ask, smokes weed, drinks, stays out to all hours even when he's supposed to he home by 9pm. He can also be funny and kind too but these things just get overlooked now because I find him so difficult.
I am passed trying to get involved because when I do I just get told I'm being unfair, picking at him, hate him and so on..
But one thing I have said to DP is he's not to be in the house anymore when we aren't there. He can't be trusted, he makes a mess everywhere, goes through my things, has friends round who smoke in my house and I'm just not having it anymore.
DP thinks I'm unreasonable, I've said he either doesn't come when we aren't in (I.e. school holidays when he just sits about in the house all day) or DP moves out and deals with him in his own house.
I don't know how it will work but I honestly don't really care, DP can figure that out. I just don't want this boy in my house anymore when I'm not around.
