Love chemistry is tricky though and you wonder what your feelings really are. Lust, interest, love at first sight or just general chemistry You just know that you feel a connection to someone else. Then again you can meet someone, fall in love, and discover as you get to know them that there is no chemistry between you. Your short-lived relationship has become boring and dull. So Is It Chemistry Or Is It Love? For a relationship to survive it requires love chemistry – a mix of both. When there is a high degree of chemistry between two people without love, then their heart-pounding sex will quickly fade and boredom will replace the infatuation. Chemistry and love are both key features of a deep relationship. Take away one and the other is just not enough to sustain a relationship year after year.
