The discovery of Eros is so new and so little has been systematically compiled about it that I would be reluctant to comment about its influence here.
I would look to the condition of the ruler of the 7th house for relationship matters.
Yours is Mars in its detriment in Libra, the sign opposite the one it rules. So relation matters may be affected by that. Mars is also squared by the Sun and Merc, both of which are wearing the sign of Mars' fall, Cancer, which is opposite the sign of Mars' exaltation.
This suggests that not only is Mars' ability to function at its best is challenged by this square aspect, but also Mars does not like or accept what Sun and Merc have to offer. And same is true for Sun: Mars is in the sign of Sun's fall. So Mars and Sun are bound up tightly in a connection that is mutually unsupportive and unsatisfying for the other.
What does this mean practically speaking? Well, perhaps that your ego or identity/Sun may get in the way of forming relationship, or that the way you think or talk [Merc] may not be supportive of forming the kind of relationship you might like. It may also go in the other direction, meaning that your lack of success in forming relationship adversely affects how your identity or how you think about yourself. These are just possibilities.
Saturn and Sun are almost in just as an uneasy relationship by unfavorable aspect and by mutual reception as Mars/Sun. However, one virtue is that Saturn wears the sign of its exaltation, and it conjuncts and exalts weaker Mars as well. So to me, some of Saturn's refinement, elegance, wisdom embraces Mars. This suggests to me that as you thread through what life has given you to make yourself a good candidate for wholesome relatedness, this strong dignified Saturn will give you a certain artistry in your persistence and perseverance to build something of value. With Saturn, it may take a while. But it can be really worth having when it comes. And lastly, another virtue is that the ruler of your 7th, Mars, is conjunct very favorable fixed star, Spica.
