Anxiety-induced breakup

I am madly in love with my boyfriend, but tonight we got into it. I'm a very anxious person and I burden him with my anxious thoughts all the time. Tonight I was worried he wasn't very interested in me anymore and I thought if I told him that, he'd reassure me. Instead he got mad that I was causing problems yet again and complained he never helped my anxiety, he always made it worse. Things escalated and now he won't talk to me because he "needs to clear his head so he doesn't make an impulse decision." That's not like him at all and I know he's going to break up with me tonight.
