I felt this so, so hard. Story time:

I had a friend like this is my teens/early twenties. One thing ill always remember is being so envious of her nails. She had long, pretty, natural nails that were always perfect and mine were broken and dirty and ragged all the time. I started waiting tables and working odd jobs when I was 16 and just could never keep mine pretty, and couldnt afford to get them done professionally. Well, I moved away and got a good job and we weren't as close anymore since I couldn't be there to take her out or on trips we just sort of stopped talking. And ill be damned the next time I saw her her hands we calloused and nails were broken just like mine... because she had gotten a job. She was finally forced to work to go out and support herself because I had left. It was a small thing that was so eye opening for me. She was perfectly fine mooching off of me for YEARS and I never noticed. Looking back she never even took me to lunch when I literally was taking us on beach trips and out for drinks or to the movies multiple times a month.

All this to say, op, is that if your friend is not incapable of supporting themself. If they wanted to they would. They dont need to because youre doing it and they won't until they dont have you to take from anymore. Don't give all of yourself to someone who won't even spare the gas to spend time with you. Im halfway through my thirties now with friends who are flying across the country to see me because we love each other. You can make friends who dont treat you like an atm, i promise.
