I don't know what to do 😓

My boyfriend, who I thought I knew was the love of my life, broke up with me over a month ago and I still love him as much as I did when we first started dating. We were together for 11 months and his parents still love me and support me through everything. I still have no idea why he broke it off, he won't tell me or anyone and everyone is just as confused as i am. Supposedly he's gonna talk to me about it someday but that could be months from now. There's no way for me to completely avoid him, our parents are best friends and I'm good friends with his sister and his mom. He wants to be friends but I don't know if it'll work out. I just don't know what to do at this point 😓
