Clearly Jack and Sasha are childhood sweethearts, been together a while (for youngsters!) but I think the reason I question the lack of acknowledgement from him is his peers who have also been with thier childhood sweethearts & are in similar circumstances have no problem publicly admitting thier relationships ie Kane, Rice, Pickers, Harry Maguire etc. Thier relationships are still private but they acknowledge each other.
Anyways Jack, I’ve got a hubby & family so not acknowledging me suits me just fine, just slip me one a couple of times a week
