Are my friends just duds?......?

You shouldn't give people your money all the time. I'd say hang out with people who do pay for their own stuff. Yea its nice of you to pay something for them once in awhile, but don't always do that otherwise they will use you. You should still go out and have fun but if you really want to hang out with them, then tell them you're not going to hang out with them if you're always going to pay. They should have some responsibility.
