In almost 3 years relationship, we've been together in  just 15-20 times. I love him so much and I'm close to his family already. But when his in work, he has no time for me. He did not text me. And i'm becoming suspicious and tired of this kind of situation,but i still hold my patience for him. Then one day,here comes a guy, who wants court me even he knows that i have a boyfriend. He always give me his time and texts me. And one day i woke  up and realized that i like him and day passed it became deeper. But i'm still afraid that he will hurt me . And now, i'm confuse. I'm committed but falling in love to a guy who i newly met.
