The way I learned it, 11 is a Master Number and is always analyzed as an 11 before it is reduced to a 2. Nowadays they are throwing many double digit numbers into the "master" category, but when I learned it, there were only two, 11 and 22, so 11 is special and quite significant in a dream.
11 is a highly spiritual number that has to do with high levels of intuition and service to others. It can also indicate indecisiveness due to wanting to move forward, but having a fear of making the wrong decision, and resulting unhappiness because of these conflicts.
One challenge of the number 11 is that the number 1 is a number that wants to do things its own way, so the two 1s side by side can either get a lot of great things accomplished, or they could be in conflict due to ego and wanting to get their own way. This may have something to do with the issues in your relationship and being able to resolve them.
