My girlfriends friends believe Im using her. They believe this because I've never been on a date with her yet we've already had sex. We've been going out for 1 1/2 months. Also they feel like when i graduate I'm going to leave her but that's not the case. I can't easily take her on a date cuz we got caught having sex and now her parents don't want me around her. I'm thinking about trying to sneak around her parents back to go on a date with her so I can prove to her and her friends that I really like her for her not just her body parts. I kno she knows I'm not using her but I'm paranoid her friends could eventually make her believe I'm using her which would result in her dumping me. What can I do to help my cause?
