I'm taking a gess here but i would say you and your bf have had a strong sexual rlationshipprior to this happening. if that is the case, he may be burnt out on sex.(3 or 4 times aday will drain a man of that which makes him a man; testosterone.) Speaking from personal eperience, pot is not the proplem. I lost a fiance becouase iwas a "worhtless pothead". truth is it wasnt the pot, I just got tired of having sex all the time.

try going on day trips that activate the mind of a stoner, ie mountauns, lake, ocean/beach , going to see christmas light displays etc.
