I made a thread a few months ago here
http://www.mumsnet.com/Talk/amiibeingunreasonable/4276770-to-be-worried-about-dd
DD and her boyfriend split up after that, DD wouldn't say why at first, but then she admitted he was smoking weed and she didn't like it and didn't want him around their son. He only saw him a couple of times, but then last week, DD and her boyfriend met up and decided to get back together. Today, he came over to see grandson and to have dinner, and DD told me he'd changed and he wants to be a good dad to their son. I don't believe he has changed though, but DD told me to give him a chance.
Aibu to not believe this?
