Some information upfront: I'm 21, our group of friends is between 18-21, we're all from Germany.
Problem is, all of my friends and I meet up frequently to smoke a hookah (pretty common here in Germany), which I try to quit at the moment. Works to an extent so far, sometimes I just give in and smoke. I feel like they won't invite me to go out anymore, if I tell them I quit it for good, because literally every weekend got something to do with hookah lounges or something similar. Not that I think they wouldn't want me around them anymore. But I feel like they would figure I don't want to come because I quit smoking and thus not invite me in the first place.
All of my friends are getting minimum to under minimum wages. I myself am getting paid way better than them, because I'm working in a big company whilst writing my bachelor thesis.
Every time I try to suggest something they always decline by saying they don't have any money to go there, don't have enough money to drive there by bus or just don't have any interest do go there. Sport activities also just get dumped as soon as I suggest it.
How do I communicate to my friends that I, although I stopped smoking, still want to join them when they go out, because I value them and enjoy their company?
I also would like to communicate that we should do other stuff too, without being annoying, since I am not 100% sure these excuses of not having enough money are always true.
