Zooloo,
I have noticed in your chart that the 2nd and 8th house contain many placements. There doesn't seem to be exact oppositions but I have always had the theory that when two opposite houses contain many planets, the native feels conflict between the two areas of life concerned.
The 2nd house is house of material security, sensual pleasures and many things that you Aries stellium may consider boring. The 8th house is house of emotional security and sex as well as reconstruction but only after destruction. The high, intense sexual energy from the 8th house (also empowered by all the Aries placements) will fight with your need for practical security. Although other people can manage the two areas without conflict, you will always feel like you can't.
Also, the quincux between the Moon and Mars isn't helpful. Although this not a most stressful aspect, I have found that negative aspects between Mars and Moon could make the native find it easier than most people to cheat on their mate (Not that it's EASY.. just EASIER). Plus, Your Capricorn ASC may have a pessimistic effect on how you approach issues in general.. including this one.
Here we, as always, face the issue of fate Vs free will. Maybe you need to understand that whatever sadness or failures you keep facing in your love life (or lives) are coming from the confusion within your own psyche.
What you need to do is to find the heat and sexual intesity within your secure marriage. Security should not be considerd a dull thing. In fact, when you are with someone you trust, you can have soooooo many adventures you can't have with someone that you don't really trust.
You need the help of a caring, motherly partner who is sexually intense and full of layers that you find one after the other (like shrek
). I think a good shot to take is for you to rediscover your husband. With your long-going concern about how sad YOU are, maybe you have missed a few parts of his personality... and feelings. Afterall, you did forget to post his birth data although he is directly related to the matter you are asking about.
Let your husband understand your need for intense yet secure physcial adventures whether you tell it his face or by just wooing him into it.
Hope I've been helpful.
