Help me out...?

Have more respect for yourself then to be someones call. Also think of the girlfriend..would you want to be in her shoes right now? Believe me..one night of pion isn't worh the world of hurt you will suffer and cause the GF. Don't listen to your body, listen to your mind..after all it is what tells your body what to do. Don't be this guys victim. If he wants you behind his gfs back, then he is a PIG and not worth your time. You deserve better!
