After nearly 2 years of dating, it appears Johnny Manziel and Colleen Crowley may have broken up ... and the proof? They've both deleted pics of each other off of Instagram.
The two reportedly began dating before the 2014 draft -- and stayed together through all of Manziel's drama ... including his stint in rehab and a police incident in which she told cops Johnny struck her during an argument.
But word on the street is things have cooled between the two -- and both Johnny and Colleen have each removed several pics of each other from their Instagram pages ... a typical move from couples who break up.
Plus, Manziel was spotted out in Dallas this weekend without Colleen ... so, rebounding?
