Am I one of “those” mothers???

We have 2 children 4 and 3 weeks old.

He wants to see the children more than the currently arranged 1 hour a week at a local swimming pool.

He’s a drug addict (Cocaine), extremely manipulative. Has lied to me about taking the children to places they aren’t allowed-due to drug use-

He has previously put our then 3 year old in the car with no car seat because he couldn’t be bothered to strap it in (it was in the trunk of his car)

He drink drives. He has been to prison prior to meeting me for dealing drugs (large quantities)

He has (without my initial knowledge) done drugs infront of the children.

And agreed to watch our 4 day old baby while on drugs too and only told me after I had left them together while I showered that he was in fact on them.

I’m unsure of how to proceed. I don’t want to be “one of those mothers” who stops the dad seeing the kids. And he pressures me and makes me feel guilty.

But I’m so uncomfortable with it. Advice please!!!!

I’m just after confirmation that I’m not being unreasonable. Or if you think I am?
