Thank you for this. I have blocked them out of my life so I'm not sure about questioning them, but I did do some of your suggestions already. When I met him he said he doesn't really use social media, and I couldn't find any accounts associated with his number, nor his brother's and I don't know his wife's name to check. I did ask about sending a gift / card but was told the hospital was strict about it, but they didn't say which hospital it was. We met in my city as he goes there for work every now and then, I don't think he has any dating profiles.
Like you said, if he wanted me there I guess I would be at hospital with him. I think cutting them out is easier for me than trying to distance myself though, I find I am often all or nothing
