Should I end it with my boyfriend? How do I do it?

Break up with him. He's bringing you down. If he dates one of your friends then she wasn't your friend to begin with and he never cared about you in the first place and it's better if you figure that out now. He's taking away from your life rather than adding to it. I've been in this situation before. He's really sweet and charming and it makes you feel like if you lose him you won't be able to handle it. You'll be fine. After you break up with him you have to go cold turkey. Delete him from your facebook, myspace, cell phone, email, EVERYTHING. He'll try to talk to you but you can't talk to him or you'll get back with him (he's charming). He's really just an insecure little boy that needs to grow up. Don't ever get back together with him. You don't need the drama. It'll take time to get over him but it'll get easier as time pes and you start hanging out with your friends again and your life goes back to normal. Use it as a learning experience and don't date another guy like him.
