Is it too mean?

this is basically a follow-up question from the last question I asked; “Be Friends After Break up?”. I have been going out with my boyfriend for nearly one year, and recently I’m not allowed to hang out unless she makes 100% sure that I’m going with friends [my mom doesn’t let me date until im in college as she wants me to concentrate with school, which I am because I get so-called good grades and now I think she is suspicious about me dating]. I have been thinking about breaking up with him as my feelings for him has faded away. Since I cant really leave the house,I cant break up with him face-to-face. Do you think its too mean to break up with him by phone[but im scared my mom will overhear] or instant message since our one year “anniversary” is next week. I really want to know as I still want to be friends after…..
