Cheers. You might wanna reach out to your friend, even if you don't have time, just a coffee or a small chat can do wonders for a person sometimes. When people fade like that, sometimes we don't understand, but it can be a sign of a deeper issue (perhaps not). Sometimes when people suffer trauma or abuse the become unable to resolve their experience and unable to relate to others who do not recognize such abuse or trauma on a surface level. This creates an unavoidable disconnect for them.
In regard to money, it certainly doesn't help to throw a bunch of money at an addict. But to give small amounts of regular support in the form of money can give, especially a woman, little bits of control over her situation. It keeps her in contact and connected with someone that actually cares and doesn't ask for anything in return.
Thanks for the comment.
