AF I am very
at Kill Him 
I apologise for upcoming statements
He is an adult, yes? Why is he staying at your Mother's house? (very kind, btw). He pays no CM, no birthday/Xmas expenditure, has massive breaks between visits - can he afford a B&B, Travelodge Family room for 2 nights? A taxi, bus, from airport to said place? Surely, with months of paying sod all, he can, and bloody well will if he wanted his contact
And, instead of being grateful he is doing his little visit, despite his alcohol behaviours, tell him that next time he drinks/is drunk on his contact weekend, don't bother. I'm sure you, like me, have the odd few wines at home when they're asleep. i'm assuming you don't frequent police stations
because of this.... Well out of order IMO.
My Ex lived alone after splitting with his GF. He swiftly moved back in with her, because he wanted somewhere for the DC to sleep over. I told him to Jog On, the children are not sleeping in Daddy's different homes with different people every week. I have not had an overnight off in 2 months now, but I'm bloody sticking to it. He caused me hell up, saying I'm ugly, fat (yeah, whatevs) - I got my solicitor onto him. Backed the fuck off then.
Sorry just I am so used to having to pull all the stops out to discourage fuckwittery. Being like this, very 'hard'
has worked very well for me, for creating the boundaries necessary. Mine does not even come in my house. Has no need to. I ignore pretty much every text he sends - ANY text from him is trying to open up a dialogue with you
I behave this way, to protect myself.
