You've got sun-Pluto in the 7th house of long-term relationships, and Mars square Pluto.
I think the solution is to get to know Pluto a lot better. A rule of modern psychology is that we either exhibit the positive or negative traits of a planet, or else we deny and suppress it. But the chart will manifest itself in some fashion, so if we don't own our unwanted planet, it is liable to show up in events or other people who seemingly manifest the planet's negative qualities.
One place to start would be the book by Steven Forrest,
The Book of Pluto.

In essence, the issue isn't your transits, because none of them lasts long enough to sustain a long-term relationship.
