Awww that had to suck! My ex and I, when we were together,we smoked together whenever either of us smoked. Sometimes some other peoples smoked with us. But the first time I EVER smoked, was with him and a neighbor. It was great. I've had SO many good times with him and a smoke. In fact, he still smokes with me sometimes(well the last time was like nearly 4 months ago..). Any weed I've gotten was from him. Apparently though HIS connection got cut off, so no more weed for either of us for a long time. But yeah he and I are best friends and I hope to smoke with him many many more times in our life! haha....
If I ever get in another relationship, I'd like that person to smoke weed(but I really actually hope they don't smoke regular cigs...blah :X) and even drink ever once in a while...(but not TOO much of course!!)
