How do i stop being so overly thrifty/cheap? I think people are getting annoyed at it already.?

There's nothing wrong with being thrifty.. But if you overdo it, then that's another story. Just plan out your budget, leave some amount (small, ideally) that you could spend on freely (guilt-free splurges). It's best to reward yourself every once in a while for all your hard work and all. I got to say, that habit of yours will prove that it's not all that bad. Like what the other contributor said, don't mind your friends and talk to your bf about it that you're also saving up for your future. If he's open-minded, he'll listen to your reason and will understand you. But again, just don't overdo your being thrift. What's soon to pass, will pass. Live life to the full, live life with no regrets.
