The symbolism for the Blue Inner Circle's chart (which I assume is yours) is as follows:The 5th house is Cancer with the Moon placed in your 7th House. This gives a strong emphasis on your need for Leo placements and/or where your Sun (since it rules your 7th) sits, which is Capricorn.
Your 5th House being in Cancer makes the echo your 4th House which is in Gemini. This person has no Gemini placements. Your Mercury is in Capricorn though, where this person has a lot of planets, possibly giving you a weaker but still some feeling of romance toward them. The Red Chart's planets have nothing in Leo except their descendant. They do have placements in Capricorn though, which may have made you feel attracted.
Libra is placed on your 8th House cusp, which is also an attraction house. This means that you may desire a Libran type of person. You also have your Mars there which is the natural male archetype and what we desire. This person has no Libra placements either. It makes your 7th House that much more important since Libra naturally rules it. Again, not much action happening in the actual signs but a lot points to Capricorn.
Your Angles are conjunct but they are very similar. Usually you will see them reversed, like Ascendant conjunct Descendant or Midheaven conjunct Ascendant and Descendant conjunct IC.
You both are on a very similar path. It looks like a lot of soft aspects happening and not a lot of planet to angle contacts. It's just not something that would seem to have staying power.
Synastry isn't the be all end all though and I'm just doing a quick analysis so I think you should keep reading that thread and study up. Lotis White explains it all really thoroughly so you have to take quite some time to work on the information she gives but it's very worth it!!
I wish you the best of luck.
