Cancer women jealousy

This goes for cancer women and their take on jealousy.

1st question - Do cancer women get jealous when they see their crush/friend/boyfriend with different chicks? What's the reaction?

2nd question - Do cancer women like to make their crush/friend/boyfriend jealous by being around with other guys and all that sort of thing just to grab his attention?

All of the above; when they're not whining about something...

My best friend of 15 years is a Cancer female. She is extremely clingy and jealous! Her ENTIRE life revolves around seeing her BF even for a few minutes. I find it highly annoying and unhealthy, haha.

Does she try to make him jealous? Absolutely not. Quite the opposite actually. She gave up all her straight male friends, even ones she had for years, to appease her man.

1. I never get jealous but can recognize right away when someone's trying to make me jealous and it makes me think less of them.

2. If I'm mad at someone for playing games I will do things to make them jealous.
