Yes it is....that is the point when you have to make a decision to be with one or the other...a very difficult decision yes. The choice you make will hurt and bring joy. I was apart if this...I was the one who ended up being hurt....but then again...who says love is a easy road
Ya, theres a story on Wattpad and its called Against all odds, You should read it!! Its about this girl being in love with 2 people(which happen to both be her forbidden love teachers). And how the girl copes with choosing, and stuff. Lol sorry my answer turned into a reccomendation.
Yes, it's entirely possible. Sometimes you lose feelings for someone once you find out more about them, so then you have feelings only for the other person. But until then, you try to decide between both of them.
