You are contrasting attributes, which cannot be done when speaking of God Almighty.
For contrasting implies the existence of a positive versus a negative and there are no negative attritutes in the Being of our Maker. He is all good and only good.
So since God is a jealous God, that jealousy is a good thing. It is certainly not the same as sinful, human jealously, which is selfish and wicked.
When the bible speaks of God jealousy, it speaks positively of God's protective zeal for those He loves, or it speaks positively of God's justice executed righteously. In both cases, Godly jealousy is a good attribute.
For no creature has basis or right to find fault or to define God as negative in any way!

God is good, and God is only good. Mark 10:18
