It's not ideal, but it happens. It's not a death sentence to your relationships if it does. You just have to remember that your relationships and partners will be characterized by those planetary energies. I'd try to bring the energy into your life in positive ways.
Well, you two are definitely the same year. Actually, you're born just a few days apart.
The only difference is the Moon (yours is better placed). Her planets are also more angular than yours -- the 7th planets are near the Descendant. Which will be more extreme, for good or bad.
Her relationships were also short and more business-like or stormy before she met her current boyfriend. She met him online and the relationship started fairly quickly. Perhaps you could try that? It's pretty normal in this age to have a few not so great relationships before you meet someone solid. A lot of it is about timing; your time will come.
