You both are monkey. Two monkeys have a natural bond between them because they both have many similarities. However, they need to change themselves if they plan to be together.

1. They shouldn't be self-centered.
2. They should stop being suspicious about each other.
3. They face difficulties objectively.
4. They truly treat each other very well.

You are just four months older than him. It isn't a problem.
