Was Jake's habit of smoking a cause for Reese to leave?

"An acquaintance of Reese and Jake acknowledges that they
were very smitten with each other for quite awhile and seemed perfectly matched.
Jake Gyllenhaal and Reese Witherspoon spent the final day of 2008 going shopping with Jake's mom Naomi Foner at Santa Monica Farmer's Market in Los Angeles on December 31, 2008.

Unfortunately, Jake had a habit that Reese could not live with, and he wouldn’t give it up. He smoked way too much. And we’re not talking nicotine here. Not only did it rub Reese the wrong way, but she worried about her children being exposed to his bad habits. So, regretfully, she moved on. Note: those of you who insist that Jake is gay are NUTS".

Reese Withespoon has been a long time representative for AVON products and beauty campaigns.

Who knows which were the whole reasons for Jake and Reese to split up? Janet Charlton has been proven right sometimes and proven wrong other times, like for example last year, when she announced an imminent rupture between Ben Stiller & Christine Taylor, and she had to delete it from her site because she was flat out wrong:
"Janet Charlton decided to pull her Ben Stiller and Christine Taylor getting divorced story from yesterday. She didn't give an explanation. Just one minute it was there and the next it was gone. I got an e-mail from Ben's publicist and I thought I would share it with you, because you know, I'm a sharer.

To Whom It May Concern:

The blog posting on your site pertaining to Ben Stiller and Christine Taylor that you picked up from Janet Charlton is FALSE. We have spoken to Janet and she has taken down her post.

The moral of this story is don't believe everything you read". Source: www.crazydaysandnights.net

Whichever the motives were for Jake and Reese's break-up (some people say it's due to Jake's closeted gayness/bisexuality, others due to Reese's uptightness), it's obvious Reese doesn't like smokers -nicotine or pot- (although his husband Ryan Phillippe allegedly made use of pot too). She's not like Kirsten Dunst (more with an European sensitivity towards the marijuana use). Seeing pictures of hotties exhaling smoke has always seemed to me attractive somehow (let's start with two stills from "Brothers"):
