My bf 11 years disappeared

I am in shock and denial. I’m angry at myself for letting this happen. Didn’t even propose to me, never tried to move together …we talked about it but never happened.

I had hopes it would happen and now here I am. He started having personal issues and he became really dry with me. I thought it was his problems but now he just stopped replying to my text since last Saturday. I haven’t texted him bc he has gone without texting me for 3 days max. Now it’s a full week.

I wasted so many years with him. I wanna cry and I can’t even let out of my emotions. My body is in shock! My mind is everywhere…did he meet someone new? What is going on! What did I do wrong???!!
