Split with the father of my kids 2 weeks ago. His idea. He upped and left completely out of the blue.
He sees the children Tuesday and Thursday after school for a couple of hours and Saturdays for 4 hours.
Contact is at my house as he has moved back in with his mum and it is not a safe environment for the kids (we both absolutely agree on this. There's drugs, a lot of alcohol and violence on a regular basis)
Every time he comes round, he tries talking to me as if everything is fine, tries to be touchy feely, grabbing my hand etc, and telling me I can talk to him. 
I went upstairs today so that he'd actually spend some time with the kids instead of expecting me to come up with ideas. He came upstairs and stood in my bedroom trying to talk to me, telling me I looked comfortable in bed 
I told him "I've come upstairs so that you'll spend some time with the kids instead of talking to me. What are you doing?"
He huffed and puffed and stomped back down the stairs.
It's bloody frustrating.
He left. If he's regretting it now it's tough. He left us. He left me when I needed someone more than ever (I have severe mental health problems. Psychotic depression)
How can I get him to see that I am facilitating access to his children, not giving him opportunity to try and "win me back"
