Girlfriend...
You're ready to roll into a relationship, and you know it. That doesn't mean that you're sworn for life to the particular guy you have a crush on now. But you can see yourself as part of a twosome. If, at any point, the relationship doesn't feel comfortable, remember that you're free to leave. But, unless the guy has really been awful to you, do it in a way that's honest but gentle. And if the guy has been a pig? He doesn't deserve any special consideration when you dump him.
