Thoughts are that it has been long enough and something is telling me that not bringing it up is more bata capitulation that just needs to stop. Time to put a foot down. It has been nearly 7 months and much good has come from the break, but enough is enough.
I agree with you but there are a couple things I would like to comment on. Your delivery has to be spot on. You have to communicate to her that you love her you adore her and you desire her and you can't be just friends with her. If you come off demanding, pouty or being a dick you will not get the result you're looking for from her.
Also, what if she declines your request? Are you willing to walk and never look back unless she changes her mind? A true alpha would never agree to be in a relationship with a woman who will not have sex with him.
IMO you need to have these things worked out before having the conversation.
