Been close to a year now. Since they broke up Greg has lost the 50lbs he put on while they were together and June has spent that time trying to get with Vaush, a fat horse cock enthusiast, who has all but publicly rebuffed her advances and falling for the old gay Swiss catfish scam. If she can't even get Vaush she isn't going to be getting any even semi-relevant e-celeb. You'd have to be genuinely retarded to go near her at this point, she's as radioactive as Chernobyl.
Also going to point out that Greg's channel reboot started while he was still with June, he started making tweets saying he hated what his channel had turned into and was going to change it. So he effectively made the decision "I don't fucking care if it means I won't get to leech off any of my more e-famous girlfriend's views, I can't go on living like this". That must've been one sober ass moment of clarity.
