Dream of girlfriend, married, mother, boyfriend, church

I dreamt of my boyfriend 's ex girlfriend 's wedding. She was walikng down the isle with her mother and I was watching her inside the church. Then, the scene changed and we were outside the church. She was still wearing her wedding dress, but she was crying and looks upset. She threw her bridal bouquet and hair dress away. She was crying when I approached her. I told her in a nice way that since she is already married, she ought to leave my boyfriend alone since he is already happy with me. I have an animosity for this girl because she once tried to beg my boyfriend back to come back to her even he is already with me. My boyfriend told her he loves me and that she has to live her own life. They have been separated for almost five years now and I and my boyfriend are happily together for over four years now.
