(Using Placidus here) Hitler's Venus is R in Taurus in 7th, ruling his 8th, and conj. Mars in 7th. Apparently he kept her as a strongly 'guarded secret :
http://www.evabraun.dk/But Hitler became genuinely fond of Eva and found relaxation in her company. "Fraulein Braun is a young girl," Hitler once said to Linge, "too young to be the wife of one in my position. But she is the only girl for me. So we live as we do. But one day I shall give up the leadership of the Reich. I shall cease to be the Fuhrer and retire to Linz to a house that can be managed by a small staff. Then I will marry Fraulein Braun ..."
What was he 'looking for' in a relationship? Apparently he found it in her. His Venus in 7th ruled his Libra Asc. So, somewhere in her he saw a reflection of a part of him that he needed very much to see...His Venus ruling Libran Asc. and Taurus 8th, conj. Mars in 7th in Taurus, ruling his Aries Desc. She combined his Asc/Desc, but basically, it seems, she was an 'ideal', although he supposedly did marry her on April 28th at Midnight, followed 2 days later by the (supposed)suicide of Hitler and Eva Braun. ( His Venus ruling the 8th.)
Meanwhile, Eva ...what was she seeking in a relationship? Her Venus rising in Capricorn, trine Saturn in Taurus in the 4th, and ruling her 5th and 6th ('fitting in' and 'duty'). While her Desc. in Cancer - seeking a sense of 'family' - and Moon ruling in the 8th (prepared to relinquish/'give up' all for that), in Grand Trine to Mercury in Cap. and Mars in Gemini in the 5th...and not to mention her Neptune in Cancer in the 7th (see Degree Symbols Topic for this one) ..what else could she do?
Would appreciate any and all comments on this, but most of all, would like to hear what anyone's feelings or experiences are about what their own 'ideal' is of a partner; what do you 'think'/'feel' it is that you look for in 'another'/'the other' ?
