Yes I'm sure you don't have a T Square and if you read her answer carefully you will see that she interprets for Saturn square Moon and Square Descendant. I certainly don't have a problem with her dealing with those aspects. Indeed if I had been able to access your chart I would have said there was a focus on the Descendant from these aspects, but as your post here did not make clear what the exact nature of the configuration was and the link to me to a site which I had to join to see the chart, that information was not available.
Now that you have posted a visible chart I can see that Saturn is your Ascendant ruler, so you (Saturn) will have trouble with relationships - The square to the Moon is also of significance in that it's the Descendant ruler, so you not only have problems with the house but also it's ruler. You also have Mars in Leo in the Seventh, and Mars is not at it;s best here. You might well come across as over aggressive, or too pushy in relationships (though this may not be your intention at all). Your expectations of the partner are that they will be of a lunar nature and possibly somewhat submissive, allowing you to take the lead. Mars also rules your MC and the tenth includes Venus, So you do have a link between the seventh and Venus and you probably project a somewhat softer image within the work environment, so yes in a way using Venus to help moderate and stabilise the Seventh House issues would work. But this has nothing to do with T Squares whatsoever.
I would point out that it does help to either post your chart directly or your natal details. You can't expect significant comment on two planets and an angle, which are linked by square and opposition but it's not clear which and another planet that is in sextile to one of the other three.
Edited to add:
I also agree with her point about you using a relationship to establish social status and possibly ignoring the partner's needs.
