It's a pretty complementary combination. The 1 is attracted by the generosity, sympathy and attention of 2. He is charmed by the social skills of 2, as well as his good mood, his good life, his very strong sentimental side and his big heart. The 2 is attracted by the integrity, honesty, awareness, rigor, reliability and self-control of the 1. The 2 feels the inner need of the 1 (which can be hidden) to have more moments of pleasure in his life and can feel the desire to help him. The 1 is happy to have a person who can soften him and develop a little more his social life, while the 2 appreciates the security and emotional stability that can offer him the 1. These two types appreciate and admire each other's desire to help others and their sense of responsibility. They share a common vision of wanting to contribute to do the good in the world.
The 2 may feel neglected by the 1 who may be overworked by his professional activities and to not give time to the relationship. The 2 might sometimes see the 1 as being too critical, emotionally withdrawn, inflexible, unable to relax, and too easily upset. The 1 might sometimes see the 2 as being too intrusive, possessive, emotionally "demanding", and manipulative.
