He hope it gets infected??

My fiance and I were having a discussion.. we had a fight earlier in which he told me to pack up and leave.. which I did but he wrote me a SMS saying that he is sorry that he will change blah blah.... Anyway.. we were having a discussion and he accidentally spat in my eye all I said was 'you spat in my eye' and he's response was 'good I hope it gets infected' Wow he has proven himself. Maybe I should leave or just sleep in the spare room tonight.
