Well all I can say is that I think you will be regreting it in about a week or so. I'm all into marriage I am a smoker and my wife dont smoke but she still loves me.... i can understand the thing with growing its kinda scary but I dont suggest giving up things you love for any relationship its the start of sure ruin. After time when your all used to her and she you, you will regret that she made you trash those beauty's and it will haunt you forever..Everytime she does something that bug's you, you will always go back and think "I killed my Plants for her...." I suggest that you break up now start up some new buds find a girl that has similar interest and then live happily ever after....
