Um... wow. I don't know. Give it time, I guess. Try to avoid scheduling dates with both of them at the same time?

[Jak is not actually any good with romantic drama. He grew up in a village with all of one girl and one other guy his age.]

It'll probably sort itself out over time. Either you'll settle on one of them or you'll get to a point where you can talk about it with both of them and try and figure out what's up. Until then, the community's as good a place to work things out as any, I guess. Though maybe not if you want to keep it private.
