Absolutely - but you need to make a decision about which person is going to receive your love, because trying to share it causes pain for all three of you.
Sorry to sound blunt, but that is the way it works - if it didn;t, the world would be a happier place.
Yeah, I do believe you can be in love with two people but follow your heart and I'm sure you'll make the right decision. Like Andy says though, decided which one it is going to be so you can concentrate on making that relationship the best ever x
