It was heavily speculated in 2013 when it had not long been announced that Tyler was going to Ravenswood, with the Coachella pictures that they were an item. And also when Tyler posted the ‘French Friendship’ picture and they went to the Nylon magazine event. They were spending a lot of time together during that period, if you go onto Ashley’s old keek account there are tonnes of videos of her and Tyler (there’s a couple taken in a candle lit dressing room which seems pretty romantic to me). Tyler even went to the Spring Breakers premiere to support Ashley and when he was asked about them being together he had a smirk plastered all over his face before denying it. And then Ashley went to film the Ravenswood episode everything went kind of quiet until Tyler came back to PLL. If they were together at the time then they’ve never actually confirmed it but I certainly think they were for that 6/7 month period.
