A couple that complements each other perfectly despite the great personality differences.
Both the Libra woman and the Aries man need physical contact in order to connect and get to know each other better. This contact is another language for them, and you could even say that they are able to express themselves better physically than through mere words.
Right from the start, Aries will be seduced by this woman who relies on her charm, eroticism, and sweetness to achieve her romantic goals. But in the long run, Aries may be a bit annoyed by her tendency towards passivity and her lack of initiative, both in love and in everyday life.
That spark at the beginning of every love story could last a little longer in this case because no one wants to escape from this magical, exciting, and sensual moment. Both are aware that one day it may all come to a sudden end, and they prefer to make the most of it while they can. They are aware of how ephemeral some love stories are and prefer to enjoy the present.
Aries can bring many his partner many things. He, sometimes impatient and impulsive, will tend to push his partner to make decisions, to do new things that she didn't even think she could do, sometimes rushing her into projects that are too ambitious or disruptive for her.
This might cause disagreements and discomfort at the beginning, and more so if she refuses to go along with her partner's guidelines, but in the long run, it will ultimately lead to an improvement in the relationship. It will also help Aries find the balance and stability he needs in his life. Their relationship will become an antidote, where he can rest, regain strength, and launch himself once again into the battles he imposes on himself. Libra will be his faithful advisor when he is overwhelmed by reality. She will provide him some moderation and pause, and he, in turn, will provide her that passion and energy, that drive she needs to move forward in other facets of her life.
Another problem that could arise between them is the Aries man's need to sometimes enjoy a bit of freedom, combining it with his life in a relationship. He enjoys hanging out with friends and spending time on hobbies. If she is not able to join him, she should at least allow him to enjoy this time alone without giving him a hard time about it.
If they both make an effort and do their part, this union will have a good chance of lasting over time. They just have to let go, not resist the changes too much, and they will be just fine.
