Revan did not leave till about a year after the events of kotor1.

Also during this time I can assume that Bastila and Revan were continuing their relationship...openly or not openly is not clear. During this time Bastila got pregnant. Not on the Ebon hawk (They still might have had some alone time) only because that means Revan would know that Bastila was caring his child which might have affected his choice to leave Bastila and the Republic for this threat.
This is why kotor2 takes place 5 years after kotor1 and Revan left one year after kotor1 which means 4 years before kotor2.
I hope this helped
I think that makes the most sense actually. I also think that they would have kept their relationship on the d.l. but Carth made a suggestion in kotor2 that he knew.
