I met my brother friend last Friday we been talking since then and today will be our third date. We clicked right away. He wants us to be more and we have a conversation like if we were together. He might ask me to be his girlfriend today. I like him too but I'm scared it's too soon and rush into it to fast and may not last. I do want to be his girlfriend and my mom told me it's not how long i have known him it's all about respect,honesty,communication and trust. Anyone started dating soon and still going strong in their relationship?
