Don’t compare :
Crush is nothing but a brief infatuation for someone. It is what makes exciting and very often it makes fizzle off too quickly. Having a crush on your partner is something that is out of ordinary. In fact, there is not much control one has over how they feel about a person and the kind of attraction doesn’t need to be a physical relation.
Comparisons, particularly, within the family must be avoided. You should never say something like, “You’re not as beautiful and hot as your mom”, or “why didn’t you get your dad’s baritone?”. This kind of conversation will never end.
Of course, you might have decided to reveal your significant other that your heart skips a beat for the parents of their crush. There is a chance to bring jealous outside. You got to handle that jealous. It is normal to feel in that way. If you find your partner feeling uncomfortable, it is time for you to build self esteem for him/her.
Never try to seduce the parent if you have crush on anyone else. This kind of behavior will be detrimental to your existing relationship with your partner, with whom you’re having the relationship since a long time. Any kind of crush will be beautiful until or unless you give them enough importance.
