You have a basic relationship problem: You're a hothead. Easy to insult and quick to criticize, you get in fights over the silliest things, and pursue each battle to the death. These problems are at the very root of the failure of your past pairings.
Though you make connections that are passionate and intense, they're also inclined to tumult, since you tend to view any difference of opinion as a threat to your ego. Not only that, but you also find yourself cursed with a curious compulsion to talk incessantly, or to blurt out the most inappropriate things, or a habit of saying the wrong thing at the wrong time. You're going to have to work on your communication skills if you want future romances to be more successful. You'll never meld together smoothly with others if you don't put some time in. Schedule regular time to sit down calmly with a disinterested third party and work out your issues. If you feel yourself moving toward a rager, resolve to table the issue until your next session instead. If you can get a little distance, gain a little perspective, you can learn to appreciate what others have to give, and how to avoid alienating them.
