Did Ashley and Joe break up?

"Jashley" got serious so fast, but now these two seem to be majorly cooling off. For starters, Ashley's been out of town non stop filming Breaking Dawn, leaving her BF alone in LA. But Joe wasn't sitting at home while his GF was gone he was spotted out with his guy friends having a blast all over town. Could a taste of the single life lead Joe to break things off with Ashley? Time will tell with his hot and cold couple...
