I'm finding myself (or maybe him?) unsure of what "proper" behaviour is.
We worked together for about 12 years and always got along in a bantery way. Approx 5 years ago, he had a serious health issue. On the day he found out we were working 121, it was obvious he was very distressed and although generally quite a private person, he confided in me. That was the start of what has become quite a close friendship. We don't work together anymore, but take our DC to the same sports events and maybe have a drink together 3-4 times a year. Probably averages that I see him twice a month. TBH, for me it's like it is with my closest girlfriends. We talk about the struggles our DC are having and generally put the world to rights.
However, our "arrangements" seem a bit weird to me. We only text during work time (i.e. never when he's at home with his wife) and I'm not expected to call him. ATM his father is seriously ill. Any other friend I'd be offering childcare, to do the shopping, make a casserole, anything to make his and his family's life a little easier. In his case though, I don't even feel I should call to see how he is?
AFAIC his wife has nothing to worry about and she knows (I hope) that we go out for a drink together and spend whole days out occasionally, so why is he so worried about me phoning?
I've never met her. Mainly because of geographical reasons, but they're not insurmountable. She suggested we all, the two of them and me and my DH, went to a quiz night recently, but my friend made every excuse possible why it wasn't possible. That's not right is it?
What do I do? He is a good friend and I want to support him though his father's illness,but I really don't want to get involved in anything that will turn nasty.
