Ask yourself why you've been dating for 6 months....and he hasn't made you exclusive...

You missed what you read as well, he said, "send me more"...so his exuses are exactly that and he was calm because, oh well he has her and others to come, after all dating means not seeing each other every day, how convenient to play...

For your safety, please go and get checked as well, just in-case and firmly if he calls you, (don't call him), you're not someone to be played with....
