I am angry by what I read

Good day mamas and papas in the house, my boyfriend sent me a text by mistake last night that was meant for a friend of his and his male colleague. The text said, " How did it go today!?!? I hope you're giving each other celebratory road head." (meaning is my boyfriend giving me head on the road to celebrate)I was really surprised when I read this text. This is not the type of guy that I thought he was, and it was a real blow to the way I view him. We are dating long distance and there is a lot of about him that I don't know yet since we have only made love 2 times. His response was that guys just joke around like that to each other. Are ALL guys like this? I really hope that there are a decent amount of guys out there that aren't. Why is it so hard to find men that have wholesome qualities!?!?
