So I have a boyfriend who I love dearly and have been with him for over 2 years now. We live in a two-bedroom apartment and his best friend lives in the other room. Recently, I have been having these feelings towards his best friend that I know are wrong because we are both in relationships. I have dreams about him and I accidentally said his name in my sleep. I find myself blushing when he looks at me or laughs at of my jokes. I have tried to confide in a friend but they called me a freak and that it is impossible to love two people at the same time. Is it impossible? Is this a real thing? Also, what do I do about it, do I tell my boyfriend and his best friend or hide it? TIA
