QUESTIONS:
I'm with Frizzatnik and want to know if you get this 'quiet awkwardness' with any other people??? 'Coz I think some amount of silence while whacked(high) is quite normal. How often does she/you smoke weed? How often do you see eachother?
Slightly Unrelated, but: 'What do people think of spending time with a GF who doesn't smoke, when you are high? (they may or may not know)
Me? They never seem to notice that I'm fucked, so its all cool.
BULLSHITTING: 8)
Marijuana is a depressant and can make everyone silent at different times. However you should be able to enjoy the silence with close friends/partners and not let it trip and stress you out. By sitting there thinking "Oh shit, i havent said anything for a while" your just making something out of nothing. Just relax and enjoy yourselve's without filling every second with 'hot air' and unneccesary bullshit. With a GF it is even easier as you can just lay and cuddle or be more intimate.
I was in a relationship where a GF and I got high everyday. I didn't really have any quietness or awkwardness with her coz we had been tight for ages and she was mad fun...but sometimes I found her less attractive when she/we were high (by no means an issue for me, but has anyone else ever had this?). I think the key with this success was the large amount we smoked and chilled together.
Other relationships that have involved the girl being an 'occasional toker' (eg. once a month/once a year), smoking has not been a good activity. Mostly the fact that the inexperienced chicks seemed to be a bit silly and 'dumb stoner like' while high. Therefore I tended to keep my everyday habit to myself or just not encourage her to partake. Personally, I can enjoy my chosen GF's while not high, or at least while not getting fucked together (hehe with buds that is).
WARNING:
Be careful though brother, pothead GF's can be dangerous...My older brother's GF had never smoked before she met him and us. 2 year's later we are calling her 'bongator' because she loves pot morning, noon and night. She is keen for a bong at every moment in the day...ounces smoked weekly, shitting on our measly 1/4-1/2 ounce per week budget.
Peace Out and Good Luck...
