My feeling are blooming for someone, is it wrong?

I am having a boyfriend and I love him so much. We are playing the same game, but a few days ago, a guy texted me and we talked a few time and now I feel that I wanted to talk to him every time. I also told him that I have a boyfriend and I am trying to limit not to talk to him anymore so that I could focus on my loved one. I feel so guilty after all. T.T
