I get what u guys are talking about, the asking about where u've been and with who makes u appreciate ur partner more and make u realize that he/she cares. But what ur talking about is not jealousy, it's called love, being concerned and protective, and that's totally normal. Jealousy, on the other hand, isn't. Jealousy is calling ur partner every hour cause u think he/she is having an affair, jealousy is that u get suspecious everytime he/she gets a phone call, u dont trust who and where they're going. That's jealousy. And it can be a terrible beast.
