I know 2 people really that I can't work out. If I'm trouble or need helping they are on the other end of the phone and offer advice but once everything is good and I don't need help/advice/support anymore , they're nowhere to be seen.
For example , when I was pregnant , I made friends with a woman that had the same problems as me while expecting and offered support. We became close friends and carried on talking but one day she didn't reply and she's been hot/cold since then.
Same with my boss. I quit my job today - kind with gifts but didn't approach me to say goodbye /thanks. I had to find her.
I know you could say they are both busy but it's just a general vibe I get . Both are hiding it seems and I just want to be friends.
