In this video, we learn how to win over her friends. One thing you can do is to pay for drinks or buy a meal when you are out with the friends. Ask them questions so you can get to know them and they think you care about them. Do not touch them and give half hugs if you have to, so they don't get the wrong impression. Give your girlfriend space with her friends and let her do things by herself, being supportive of her hanging with her friends is great. Try to set her friends up with your guy friends as well, the girls will love that!
