How have you experienced Saturn square Venus in your life? What happened to you? Do you recall?
I have Saturn square my natal Venus right now. I don't know what the Venus/Saturn theme in my life might be. I've given more thought to Saturn being conjunct my moon and Neptune (moon/Neptune squares Venus/Mercury in my natal chart). I'm also experiencing the once in a lifetime Neptune square to its natal position right now, which means Neptune is in opposition to natal Venus. So, with all of these transits taken together, plus all the other transits to other natal planets, I can't very well say what's Saturn and what's Neptune and what's something else.
If you have Saturn square Venus right now, you also have Neptune either transiting or opposing your Venus. If your Venus is in Pisces, it's being transited by its ruler, so I would think the Pisces-ness of your Venus is being magnified.
If it's in Virgo, it's being opposed by its direct opposite, although Venus naturally vibes better with Neptune than with Virgo... so maybe there's some anti-itself energy going on? A challenge from Neptune, which encourages dissolution of boundaries and not being bogged down in detail, to a Venus that tends to relate by tending to the little details. At the same time, whether your Venus is in Virgo or Pisces, it's receiving a challenge from the boundary-and-commitment-oriented Saturn, which is losing some of its constrictiveness by being in magnifying Sagittarius.
I do think that if things are not firmly tethered that they tend to fly away at this point in time, for sure. If no energy is expended in keeping things together with friends and intimates, then they tend to walk away, at least for a while.
Is that a Saturn thing, or a Neptune thing? Things flying away, or dissolving, sounds very Neptune to me.
Anyway, just curious to how you (or anyone else) has dealt with this. There are a lot of threads on this, but I'd like to add to the pool of knowledge with personal accounts.
My way of relating to friends is to drop in and out of touch repeatedly over the years. Always has been. My longterm friends are all people who handle this the same way. With the people who are in my life day to day, it's more of a comfortable and consistent relating. I don't see Saturn square Venus changing this any.
Last time Saturn squared my Venus, I was at the beginning of what would be a ten year relationship, deeply committed. I don't think that wrecked it any.
it simply means the things you want but don't work for - the lazy you - the one who thinks s/he deserves more than s/he's getting....etc. comes to a sticking point.
not anything near a true walking nightmare unless you are one who likes dreams of getting everything without working for any of them.
Who doesn't like dreams of getting everything without working for it? I certainly do! That doesn't mean I think those dreams are a real possibility.
One thing I can see in the current Saturn square: I'm currently studying herbalism, in an intensive program, in the hopes of making that my new career. I have the MC in Libra, making Venus its ruler, and Venus in Virgo, which would give it some earthy/practical and health/healing implications. Saturn square could indicate a challenge to work at it and build my skills, and a warning that I'm nowhere near ready to start yet. Saturn, incidentally, is transiting the cusp of my twelfth house, and has been for months because of its retrograde. Venus is in the eighth/whole sign ninth. Saturn also rules my AC, which loosely trines Venus (and tightly trines Mercury).
I'm inclined to interpret the twelfth house transit, in the sign associated with education and experience, as building up my practice behind the scenes. Maybe I'll be ready to take it out into the world when Saturn reaches my AC in early 2018.

A transiting Venus to natal Saturn is nothing more than a faint aroma drifting, passing you by; whereas transiting Saturn—well, that's a whole different stench.
