I think the end of TFA made it very clear a romantic relationship was never in the cards for those two. At least for me it was. and the hug at the end of TLJ was completely friendly. Like even at the end of TRoS he goes in for the hug. He doesn't show any interest in her romantically.
Just because we have a male and female character being friendly with each other doesn't mean they want each other romantically. And beyond the "cute boyfriend'" line at the end of the first act of TFA I never got the idea they would ever be romantically involved. Just two best friends caring for each other.
