<human>: Could you distill the essence of the text into 1-3 sentences?

We're recently engaged (this month). Fiancé is really great but this aspect of him has always been a little unsettling to me. He can't say no to his sister when she asks him for money and I think she's abusing him.

I think in the past three years that we've been together, he has given at least 30K to his sister (and he's not rich, he's upper middle class). This is just the cash. He gave her his old car (which was worth at least $20K, probably more) and there are lots of other small things here and there. This is him enabling her.

His sister is a nice girl as a person, but she's very irresponsible. She's 26 and hasn't had a single job in her life. She's been in school since forever (I don't know what she's doing there and why it's taken so long but she still hasn't graduated). Honestly, my fiancé can employ her in his own small business and at least have her work for the money she receives but he hasn't done that.

I don't want to sound controlling, or appear to be coming between my fiancé and his family because I know he loves his sister and feels responsible for her ever since their parents passed away, but I think now that we're starting a life together we need to talk about this. Am I thinking about this right and if he's, how do I approach him?
<bot>: Fiancé is enabling his sister for years and I think it should end for our and her sake. How do I approach him?
