But what if it doesn't?
Where does lust cross over to love?
So, you can't stop the feelings, you've started sending too many flirty emails, you just don't know how or don't want to stop. You are in a relationship but are actively falling for someone else.
Lorrae Bradbury, open-relationship pioneer, sexpert, and founder of Slutty Girl Problems, says love progresses in stages. "There's the new, lusty, infatuated feeling when you're first getting to know someone; the caring, tender feelings of wanting to commit, and the deep respect and dedication of long-term love."
When you are dating two people at the same time, your feelings still follow the same natural progression.
So, if you're having two separate relationships with two different people, where do those feelings cross from passion into love? "Love and lust can feel so similar at the beginning stages of an attraction, it can be difficult for some people to distinguish them," McCombs says. "If we practice some mindfulness, it can be easier to suss out what it is we're really feeling. If you are struggling to tell if it's love or lust (or both), take some time to sit with your feels."
