[b]Charla[/b] gave you great advice.
I’d add that you should work on self discipline and self awareness. Verbal barbs are painful and when you call your boyfriend a loser, you can expect he’s going to feel unappreciated at best and in the wrong relationship at worst. When you feel your temper flaring, be aware. Give yourself a time out so you can calm down before you flip out and say things you’ll feel badly about later! Not reacting is a discipline that you achieve with determination and practice.
In the meantime, an apology is a good place to start, and a discussion about what you’re going to try and do to improve yourself so you don’t hurt him like that again.
I hope that helps, and that you’ll join me @AskAprilcom on Twitter and on Facebook: [url][/url].
