You’re not sure if she’s interested because you haven’t made it clear what you’re interested in. 😉 Your instinct not to accept an invitation with she and her friend is a good one. Trust your instincts. They’re working! 🙂 Tell her you like her to much her share her! Give it another shot and make it a good one. Tell her there’s a great romantic (key word) restaurant where you’d like to take her to dinner and get to know her more. In other words, you have to make it super clear what kind of a date you’re interested in, and what your intentions are (romantic). If she says no, or give you the brush off, move on. If she doesn’t, then you’ve cleared out the social, emotional clutter and you’re on your way!
