IS IT POSSIBLE TO ACTUALLY LOVE TWO OR MORE PEOPLE AT ONCE?

Is the feeling of love supposed to be exclusive to a person per time or not?

On Twitter yesterday, May 17 2017, a user shared about how a friend of his fell genuinely in love with three guys.
According to Noris [@iam_NORIS], this friend has a boyfriend with whom everything is going well. No issues, he's her first love and they both feel so much love for each other that marriage has been discussed on few occasions.

Somehow in the midst of this impeccable romance, she got a little too close with one of her followers on Twitter and from following each other on the social media platform, the followed each other to a couple of dates and eventually into the bedroom.

She suffers depression and anxiety issues from cheating on her boyfriend, and this her second lover suffers these issues too for reasons of his own and this brings them even closer.
Their connection was sparked by this anxiety issues.
But that's not all. There is a third guy in the picture.

As a matter of fact, the third guy is the boyfriend's roommate!

How interesting can this get, right?

Anyway, she and her boyfriend's roommate got drunk one day and had sex. After that sex, according to Noris who shared the story on Twitter, she developed strong feelings for him, too.

Now there is a lot to be said of this fascinating story of emotional connections but we'd love to know of the situation.

Is it truly possible that someone would be genuinely in love with two, three or more people at the same time?
