What does this mean?

Been with the same guy a while, don't see each other too much bc we are always busy.. Today we had sex like normal he came inside me like normal.. We were all good, got home been texting.., then he says "we shouldn't talk anymore" I said why, he said "I think we might be getting too close" we've been back and fourth about 2 years.... I'm confused what the hell? I'm hurt...?
