Although I think clubs, agents, sponsors etc still like players to be relatively settled, there doesn't seem to be the same pressure to get married that there was even maybe 20 or 30 years ago. If this was the 90s they'd have married 5 years ago, have at least 1 kid and we'd still be seeing endless rumours of him shagging minor celebrities.
If you look at Jack's teammates for club and country, the unmarried are in the majority. Plenty are in relationships, and some are single.
So there might be pressure, but more likely personal than professional - their families etc. And they've been together long enough that if that was going to persuade him it would have done by now.
So if he proposes I expect it's because he actually wants to. I'll believe it when I see it.
