Sun, Mercury, Venus, Vesta, Juno in 7th house cancer?

Hi,
I've been reading around about the meaning of the various planets in my 7th house (which is also my sun sign-Cancer), but I haven't been able to find anything holistic about the fact that all five are in the house together and some very close to one another.
As some background - I (female) have had many, many short-lived, profound and life-changing romantic affairs, and have recently been trying to conduct a relationship with one person and feel practically psychotic in it. At the same time I am deeply tied to him and cannot seem to let go. I feel closer to him than family, breaking up is not an option, but then again, being together might even be worse. In other words, very intense and seemingly never-ending. Hoping my chart may hold some insight!
Here are the degrees (I'm new at this so I hope I'm writing it up correctly):
Sun 28 degrees, Cancer 32 minutes
Juno 6 degrees, Leo 41 minutes
Venus 8 degrees, Leo 14 minutes
Vesta 8 degrees, Leo 30 minutes
Mercury 23 degrees, Leo 20 minutes
Also, what's the significance that Leo shows up between the 7th and 8th house cusps?
Much much thanks and gratitude,
Ayala

P.S. My current partner (like many of mine in the past) is a financially-challenged heart-as-gold artist Taurus

Here's a link to my chart: http://www.astro.com/cgi/chart.cgi?...011;hsy=-1;zod=;orbp=;rs=0;ast=&nhor=4&nho2=2

Also, I've received some conflicting information on Saturn in my 9th house and my 9th house being Libra. If anyone has any insight as to how these may affect each other I would greatly appreciate it.

And finally - if there's anything in my chart to indicate the second half of my life being easier than the first...

Much thanks,
Ayala
