I was suspecting some child abuse too since she told strange things about her father.

This is in part why I say people are not just promiscuous or deviant out of nowhere. Deviance from the norm is usually shown in a chart but it is also influenced by the person's upbringing/enviromment/ and also maybe even DNA, etc. I feel like this is a psychological issue more so than anything else sometimes and when someone cheats on a spouse it isn't just a matter of cheating, it is a problem that is not being sorted out.

As far as the father goes, that was the first thing I think of when Saturn is involved as well. I am sorry if you friend had a difficult past. If her different sexual habits make her happy, then good for her.

I'm really glad this thread took off! Also nice to find out Tanit has a Ven-Mar conj in Aries. That explains her spicy personality

It's an interesting point Tanit raised with Saturn in the 7th house. Most of the time I associate Saturn in the 7th with divorce or multiple marriages. This is unlike Venus-Uranus because Saturn in the 7th can give really loooong marriages (20+ years) and then divorce. But do you find a lot of people with that placement cheating? I used to know someone with Saturn in the 7th in Taurus whose ex-wife had a natal Venus-Saturn conjunction in Taurus. Not sure about her Ascendant or what caused their divorce, but I found it interesting how someone with Saturn in the 7th ended up with someone who has that placement. It makes me wonder if it's the Venus-Saturn conj person who is subconsciously attracted to a cold spouse (i.e. Saturn cooling marriage in the 7th), or a person who is subconsciously attracted to a spouse who is incapable of love (Venus-Saturn conj).

But do you find a lot of people with that placement cheating? I

Someone would have to look at the stats on that to answer properly, perhaps. Lilly calls Mars ill dignified the cheater but Saturn ill is still a liar. As the article points out, Mars is often present with Saturn and that was true in my friend's situation and I normally associate Mars with divorce more so than Saturn because Mars traditionally is similar to Uranus and leads to cutting things short and sudden surprises. Saturn could indicate many years of trouble before an ending though. As I said, cheating often doesn't happen out of nowhere and it seems almost like a cry for help to end a bad relationship sometimes. Both can cause pain and with Saturn I think of prolonged pain whereas Mars is more acute.

Jennifer Garner has Saturn lording the 7th with Venus, Mars and Saturn conjunct in the 12th and opposite Neptune. She didn't cheat but was cheated on by an alcoholic husband who caused her a great deal of pain and she loved him many years: https://www.astro.com/astro-databank/Garner,_Jennifer So, you kind of have to be careful in that respect. This happened to her, she did not do it to someone else (same with my best friend).

Jessica Biel's husband Justin Timberlake is said to be a cheater too (speculatation) and her chart does seem to maybe support that, as another example I have looked at before out of curiosity (Mars/Saturn conjunct Square Venus, also Neptune aspecting Mars/Saturn and Moon opp Neptune from the 7th). Her husband has Saturn lording the 7th and Venus/Mars/Saturn/Neptune all aspecting but not in hard aspect. He has been cheated on himself though and him, Jessica (and Britney Spears) are Venus-Pluto squares. I often associate Venus-Pluto squares with a fear of a partner cheating, oddly. Perhaps this fear could create a subconscious drive to cheat themselves. People cheat for different reasons. Venus-Pluto might cheat as a preemptive strike whereas Mars/Saturn could be a cold disregard for the other person's feelings, I wonder.

Saturn lording the 7th or in it is associated with difficult relationships (supposedly especially before the Saturn return but I never saw much relevance to that). If Saturn is dignified it might be a better energy to deal with, such as just showing delay, few relationships, long lasting ones, and/or an age gap or describing a partner as Saturnine. In the cases that stand out to me, they involve bad placements. In the case of my friend's situation, again, her husband had Saturn conjunct Mars lording his 7th and she had the conjunction in her 7th, both square Neptune, which I do think makes it worse. Both were peregrine and are malefics combining in energy. She has described him as a liar and cold in the end but he did not present himself that way in the beginning. My first astrologer also told me that men with the malefics in hard aspect to Neptune are more likely to have a perverse type of mind but may even be in denial of it, which leads to dysfunctional expression, such as cheating (or other things that are hurtful to others). If you Google celebrity males who have cheated, it is hard to find any that do not have this (also Moon-Neptune hard aspects for some reason). I am not sure it works as well for women.
