I have had to name change for this one...
I don’t even know where to start 
We’ve got a holiday booked for next week and DP has now said that he won’t be coming with us, I don’t believe he had any intensions to come with us in the first place! I don’t trust him, he is very sneaky and he has cheated in the past I feel as if he wants to stay behind so he can get up to no good.
I’m in a situation where I can’t tell him to leave because the house in jointly owned, I am always telling him that I want him to go but his reponse is always the same “no you go”
And a few weeks ago, he left our 10 year old son in a cab station for over an hour whilst he went into the betting shop.
