I took a look at eclipses some time ago and they did activate my natals in my longest relationship. Both of the eclipses fell on the Gemini/Sagittarius axis. There was a solar eclipse in Gemini at june 10th 2002 that fell right between my natal Venus and Moon, 1 degree from the actual midpoint.
A few months later i met my girlfriend who i would spend 10 years with.
At june 4th 2012 there was a lunar eclipse in Sagittarius opposite my Venus in Gemini and the relationship ended 3 weeks later.
Solar return for 2002 shows a very packed return 7th.
Solar return 2012 had a really tight moon/Uranus conjunction. SR Uranus ruling SR 7th and SR moon ruling SR 12th.
The actual events are really obvious in hindsight
