I have a friend I see every month or two (we don't live very close together). It is me who instigates meeting, mainly me who travels and I don't mind this. She is one of my favourite friends and its always lovely to see her. She has had a very difficult few years and experiences depression. On this basis I make an effort to keep in contact, send occasional text, even though she often doesn't reply.
I know from past occasions she struggles to reach out if feeling bad. But recently I wonder if I am putting pressure on her. I don't know whether to keep issuing occasional invites.
