Drunk words are sober thoughts. People have no restraint when they're drunk.

I think the issue is NOT where you were joking (?) about going, but that you said it to another guy, when your boyfriend was not supposed to hear, or was not directly included in the convesation. He may have been drunk, but there is nothing like hearing the tail end of a conversation, that in a certain situation could be construed as almost arranging to cheat, to make someone sober up.
