She's seeing how far she can change and control you.
If you quit for her, things will only get worse and she will desire you to do this, that, and just about everything for her. That's my 2 cents, tell her to fuck right off and that she shouldn't have got with you in the first place knowing full well you smoke cannabis if she didn't like it.
Although I did read a success story about a guy giving up pot for his lady, so it could work out for you...
WeedyBoyWonder Reviewed by WeedyBoyWonder on . GF wants to break up cuz i smoke. My fucking girlfriend..who I've been dating only for a month or so..says she's been thinking, and that she wants to break up until I quit smoking pot. I told her if she was really serious then I would stop now...and never smoke again....she won't fucking believe me, and she keeps saying she wants proof. But passing a drug test cud take months. And i don't wanna not be with her till i pass a drug test. Geeez....seems like shes just using this as an excuse to break up with me..i hope not..i Rating: 5
