I really understand your point. You get him who has no money and he brings someone else along who has less money. This is a recipe for disaster. He may be as big of a mooch as she is. You don't need to support 2 adults. If he has his act together and she wasn't part of the deal that is one thing. But who needs all of their baggage. I would look for a boyfriend who doesn't come with a sister. He may talk to her but how long is that going to last. You have to find a relationship that is with someone who is financially and emotionally supportive. You need help too. don't be the only rock solid person in a relationship. If you are going to pursue this stand your ground. Make sure you give firm boundaries and they don't include her. The money needs to be centered on the needs of the two of you. Make that clear. You are not being unreasonable.
You were right
