Irrational Breakup ??

My boyfriend and I have been together for almost 7 months and we have not had sex at all yet. He says he doesn't mind but this is his first time going so long in a relationship without having sex. Somehow we got on the conversation about our relationship and he says "sex is better than our relationship" he said it three times and told me he didn't mean it but it hurt what he said because he was talking about how his sex life before me is better than our relationship. I broke up with him, but am I being too irrational ?
