2 people at once???

Do you guys think you can be in love with more than one person?? I know it sounds awful but I’ve been dating a guy for a year and a half but I’ve fallen in love with someone else. I am still in love with my boyfriend and I would never cheat on him or date the other guy since he’s just a friend but.... what should I do I feel horrible but I really am into 2 people at the same time.
