Is this considered cheating?

My boyfriend and I have been having problems, and we both agreed to take a break from each other. Well the day after we decided to take a break, I went to town with one of my guy friends that I have been close to.for about a year now, and we talked about my relationship problems (which it felt really great to have someone actually listen to me for once) and then we kissed.... later that night my boyfriend called me and was calling me his girlfriend...?
