We’ve been best friends for 7 years and we’ve gotten along really really well until the last month or so… she’s negative, has no drive to do anything (job, life etc) she’ll say she has no money but doesn’t come to our bar job most nights and her week job she usually goes in late. She recently got a car second hand which she was way over charged for and she can barely afford it but didn’t take my advice on looking around for a different one, it bothers me because we plan to go places and then she says she has no money but the majority of her money goes towards food and as soon as she gets paid she blows all her pay check in less that 3 days on clothes!!! I’ve been trying to get her to save for the last few years because I wanted to go on a girls trip but she just won’t put money aside at all. I do the most driving if we’re going places, I usually pay for our days out which never used to bother me until now, and I usually plan if we are going anywhere. Another thing that bothers me but I can also see from her point of view is that I recently started talking to my ex again after a longggg time of not talking, I was with him for almost 3 years and we stopped talking for around 4 years, we’ve started sleeping together again but we aren’t getting back together but I did miss his company, she told me how much she hates him (he cheated on me) and I understand why she does but she’s also never been in a relationship at all so doesn’t really understand why I’d be doing this, again I understand exactly where she’s coming from so this isn’t so much the issue but it’s more how much she wants to tell him how much she hates him which I don’t think resolves anything and makes her look like a child. I’ve been on occasional dates with people and some of those people I’ll go on second dates just to see if I do like them and she thinks this is leading people on if I end up not interested in them but I just see it as “making sure I’m making the right or wrong choice” bearing in mind I pay for myself on dates, I never expect the guy to pay. She still lives with her parents, as do I but I pay for most of my stuff independently and still have money left over and I’ll even put some aside for emergency’s. She recently said should she join uni and I said do it! I’m in uni and I love it and I think it’ll help grow her confidence and meet new people but then once I agree that she should do it she shuts the idea down and says she doesn’t want to or she says she doesn’t know what to do. Im in uni part time with two jobs and she’s got two jobs too but barely comes to the second one, I feel like were both at very different places in life now and I’m not having and don’t know what to do?

Does anyone have advice on how I can mend my friendship with my best friend or if it’s even worth saving?

Td;lr My best friend lacks motivation and never saves money, she drags me down and I’m tired of her childishness/pettiness, she’s never been in a relationship but judges me for going on dates because she thinks I “lead men on” if I go on another date with them to see if I am interested even though I pay. Please help.
