Can love bloom when the ugly faces of possessiveness and jealousy surface in a relationship?

possessiveness and jealousy both are opposite characters, there can be possessiveness, but not jealousy in love

At the present time on Earth and with regard to the need of the hour, Love comes behind the sword of Truth because mankind has become exceedingly deluded, its consciousness darkened due to its false I-dentification. Love cannot gain entry into humanity’s heart as long as that heart vibrates in the denseness of its self-conceived fantasies. So polluted, tenebrous, and chaotic has the Earth become with mankind’s delusions and ignorance that relatively few people in the world today can see or hear the subtle sound of Love’s eternal song. It is all but non-existent to the sleeping consciousness of humanity. And so Truth must clear and make straight the path for Love’s return. Truth must prepare a fertile field on Earth so that Love may blossom again within the hearts of men. The mighty power of Truth will bring all falsehood to its knees in these last days of the age so as to restore Love upon the throne as king of this world.

Not likely, unless both are committed enough to the relationship to talk frankly & get past those. Otherwise, one person is going to be miserable, even if they decide to stay.

jealousy in love?

No, love is not like that.

Not if you keep mixing your metaphors like that.

No. They're opposites.
