He's Jealous and Temperamental!

Ma, I have been in a relationship with my guy for close to two years now. My parents know him, and he has told me that he will be coming officially to see them in less than two months time. But I'm bothered cos he's very temperamental, very jealous;

Am I Overreacting or Jealous?

Good evening ma, please help me, I really need an advice. I have been in a relationship for six years, he got a job in another state and spent more time there now, only come to our town of residence few days in a month.
