What's with your chart, Koko? It seems to be rotated. Normally we see the 7th house cusp on the right side of the chart.
The 7th house says something about the type of partner or spouse we hope to attract. With so much Capricorn emphasis in your chart, you may admire people who seem more witty, versatile, and clever. These are qualities associated with the sign of Gemini. It doesn't mean your perfect mate is a sun-Gemini, however.
With Mercury conjunct Venus, you are apt to think (Mercury) about love (Venus) a lot, particularly with that aggravating square from Mars. This is kind of a "can't live with him, can't live without him" configuration.
But this doesn't mean you can't have a good relationship. As with most people, the key is finding the right person. Synastry is the branch that deals with comparing charts between two people to look for compatibility. You might just find a dreamy Pisces or a sensuous Taurus who admires your Capricorn nature.
Synastry doesn't go just by sun sign, but especially in comparing all of your personal planets and ascendant.
Your chart actually has a lot of pleasant trine and sextile aspects to it, which should help you to get through life with equanimity.
