Here a hopefully helpful post I found on elsaboards about the Saturn Venus square:
“I think those of us with Venus sq Saturn feel deep down that we truly and utterly are not worthy. We question, why would anyone be interested in us? We may have very successful lives in many ways but are largely single, for most of our adult lives and we grasp at why someone would want to be with us because we see no value or worth there.
I think it is possible to grow into this aspect, to grow beyond but I believe it can only come after some very serious hard work. Number one is to stop running around and to stay still long enough to figure out what it is that you love to do. You must learn to love yourself. So you must spend the time, in many cases, this takes years, to find yourself. You will have to measure your own success in this initiative. No one can do this but you. If you are someone trying to love a person who has this aspect, there is not much you can do, sorry to say. This is work that must be done alone.
Many of us will say “there is no one around me to love me” or “no one is interested in me”. Stop a minute. Look around you. This is not true. It is never true. There are many men and women in your sphere who are dying for you to stop being so self-involved and to see them! The problem isn’t them, it is that your eyes are closed. It is YOU that isn’t interested in them, it is YOU who restricts yourself from loving others.
If you can get to the point where you can begin to see that loving is YOUR choice, you can begin to crack this nut. Yes therapy, journalizing, meditation, etc. these all help but ultimately what you need is to build your self esteem. You don’t do this by talking about it or reading about it. You gain self esteem by DOING something! Over time by doing it again and again, you gain confidence.
If you can gain confidence, you gain self esteem and if you can get there you will feel that you are worthy. At that point, your eyes open and you see the love that has been around you all this time."
There are two obstacles in her chart that require great patience in keeping relationships healthy. First the ruler of her Descendant is opposite Mars, meaning she needs to more clearly project whom she wants in her life, or she will attract men that are just plain not stabile. She needs to define for herself how much freedom she wants in a relationship. She needs to become aware of possibility that she is sending double messages, and obstructing the development of a relationship.
The second obstacle to a happy romantic life is Venus/square Saturn. This aspect attracts and creates limits and blocks in relationships. A person with this aspect typically worries too much and cannot establish a continuous emotional flow with a partner. One can become overly critical and dissatisfied, with some heavy issues in relationships. Saturn is afraid of Venus – doesn’t understand her. Saturn needs to be more relaxed.
Hope this helps a bit.
