Very frugal person but my friend spends every penny

How do you all deal with that one friend who spends every dollar immediately when you are a very frugal person who lives well below your means? We are like total opposites. My friend doesn't have a job but, somehow always has money for life's luxuries (selling food stamps and getting handouts)then constantly says they have nothing. I try to find ways to save and rarely treat myself so it's hard having her flaunt everything as we are trying to plan for the future and emergencies. I'm pretty much struggling with jealousy especially when I see these things at work. I feel like I need more people who have the same goals I do.
