Please help!!! very important!!?

my boyfriend and i really really like each other maybe even love and are so happy when we are together, his mom and family likes me and everything. the only problem is that im not allowed to have a boyfirned. today was his BBall game and he REALLY wanted me to go and i found away to get there with out my mom knowing. (my mom is very strict) She ended up calling me and telling me to cunm home right now or she will come get me so i left. he thought i was still ming to the game becuz wen i called to tell him he was already on the court. My mom took my fone and is on my case now. on weekends she has me doing everything so i never have time for myself and on top of that im grounded. Im 16. how can i get around this? what can i do to see him more? i know he is gonna be super mad becuz this happened before and its gonna be so hard to face him knowing that i let him down. We dont go to the same skools so i rarely see him. Please tell me sum ways to see him and go around wat my mom?
