We learned about the Relationship Attachment Model-RAM
This is a model shown what level you should know, trust, rely, commit, and touch the person you are in a relationship with.

By looking at this graph you can see how there is a decline in it. This is a good decline. This means that you need to know more than you trust and than you need to trust more than you rely on them rely on them more than you commit and commit more than you touch. If any of these are out of balance and at different levels  your relationship will be as well.
