'd' p is the father to our new born and I've had enough. He doesn't lift a finger round the house, 'babysits' HIS son if I need to go somewhere or do something (reluctantly) and when I return he's stressed, needs a drink. He has been unfaithful multiple times although I only have proof for one affair. He is holding himself and me back from a decent career as he would prefer to smoke pot and to top it off is now unemployed. I've had enough. I have asked him to leave but he wont, he says it's his house too and he wouldnt leave ds with e 
We rent a house off a friend of a friend (my friend) and have recently put a claim in for housing benefit tax credits ect ect.
Where do I stand and what do I do?
neither of us has anywhere else to go
I am not worried about my ds or my safety and I do actually care about partner, I just cant take anymore of being treated like SHIT and think we would be better off apart, but like I said he wont go and neither of us have anywhere to go to.
