What the hell is wrong with me?

I know it can be hard, but you could ask for their # because most people have a cell phone now days and if you would be more comfortable text the girl. If you text you have a chance to think of what to say and how to say it. That could help and if it doesn't take you long to text just act like you are texting someone when you talk to the next girl. Just say to her what you would text. I hope this helps.
