My girlfriend wants freedom,??,,?

ok so me and my girlfriend have been together for 1 year and 3 months, and i slipped on ice and broke my leg so i ***** go to the senior trip, but she went, and it was all good till the next day, i had issues in my house, and i called her, and i was trying to act cool but lost it and then started saying shitt like, ohh i am suffering my *** off here and you are there enjoying, dt kinda struck her hard, and ruined her whole trip.. but aagain, it wasnt on purpose, i had issues in my house and other tensions, and it all came out on her, not that i wanted to let it out on her, so then she told me how i could have waited for her to *** back and then shared and do whatever with my issues, buh again, i didnt do it on purpose.. it wasnt in my hands... and i m kinda overpossesive, overprotective, and sometimes insecured kinda boyfriend.. and i stopped her from talking to her one guy friend that i think has bad intentions cuz he didnt want me to go to beach whn my girl, him n friends wer going so he cud do his own thing.. thats why i didnt let her talk to him... and then when she hugs her guy friends, its kind of uncomfortable for me, but i am working on it.. but she said how she wont care about nething cuz she wants to live her life and wants to choose her own friends without me ruling over and controlling over her teenage life,,, btw, we both are seventeen,,, and yeah... we both have each others fb pwords... she changed hers, but i still didnt change mine... i left everyone for her too, i didnt whine about getting my ffriends back or anything.. i was happy with her and thats all that mattered to me.. but i guess everyone is different...so i need help, what do i do now? give her space and not talk to her for about a month or so? or let her do whatever she wants and i do whatever i want? please help... really appreciate your time... thank you guys...
