i recently started dating a guy who has ptsd and after a month of talking everyday and hanging out, getting really close and expressing true emotional bound that was forming he just stopped, cold turkey, no response. One day it was good babe sleep well and the next nothing complete shut off. Ive sent messages , but im not sure what to say or do. I like him so much, im willing to try and help and understand, have done alot of research, and expressed my concern. Help
