Heartbroken

My boyfriend of 3 years told me that he’s basically thinking about leaving me because my parents are not his biggest fan but they are always nice to him and welcoming, I’m so lost and heartbroken we are still together and he told me he loves me and this is not easy for him and needs time to think but I am still so in love with him and ……… I wish this wasn’t happening, he has been depressed for a month, I have loved him since I was 15 and now I’m losing him
