I don't think anyone should succumb to fan pressure and propose. Taylor is putting her all into this guy, hyping the whole relationship. I know she wants to get married and have kids, but I don't think he's the one!
And just to be fair, not every guy loves all the attention all the time and being in front of the camera. If he doesn't propose or breaks up with her for any reason or no reason at all, he's the bad guy. And I don't think that's fair.
He seems to really love the attention, though! He appears to have a big ego. Maybe that’s the kind of guy she’s needed, embrace the spotlight.
Hopefully he knew what he was getting into with her regarding not working out and the fallout that would come with it.
