A relationship is a big responsibility. You have to be aware of your partner's needs, and give them what they want.
Besides the normal problems with a relationship, people with aspergers have additional problems. Dealing with empathy, socializing, thinking about what is on the other person's mind (theory of mind), and lack of realizing what is proper in a relationship.
Understanding and preparing to deal with your challenges can help you better succeed at a relationship.
From myself and others I see that if a person works on these things they can improve. Besides myself I have heard from others who were able to improve in these areas. Tommorow I will post a personal story of how I improved in conversing with a girl.
