What do you think about love and jealousy? Some say that true love can't include jealousy and that these two things are incompatible, others say vice-versa - love means jealousy and is the proof that a couple loves each other.
I back the first opinion, because to me, love firstly means trust, while jealousy appears when there's no trust towards each other. If you trust your love, you know he/she will never cheat you.
