How to ask out a girl is an age old question. Say the wrong thing and you risk not only rejection but embarrassment. Asking out a girl over DM is no easier.
Asking a girl out over DM is all about confidence. Instead of bragging this means being direct and unwavering. Show her you know what you want and can take control.
You miss 100% of the shots you don’t take. It’s a numbers game. The more practice you do the higher success rate you will have. Take a deep breath and don’t overthink it.
