Most Helpful Guy
I can see your insecurity in finding this out but keep this one simple yet HUGE fact in mind: He was honest with you. What more could you seriously ask for? So he still has feeling for his ex, that doesn't mean he doesn't care about you. Now that being said, there is going to come a point where he is going to need to straighten it out and separate past from future, but until then give him some slack and let him figure it out. As long as you support him, he will stay open and honest with you.
