As we enter the intensifying stage, we indicate that we would like or are open to more intimacy, and then we wait for a signal of acceptance before we attempt more intimacy. This incremental intensification of intimacy can occur over a period of weeks, months, or years and may involve inviting a new friend to join you at a party, then to your place for dinner, then to go on vacation with you. It would be seen as odd, even if the experimenting stage went well, to invite a person who you’re still getting to know on vacation with you without engaging in some less intimate interaction beforehand. In order to save face and avoid making ourselves overly vulnerable, steady progression is key in this stage. Aside from sharing more intense personal time, requests for and granting favors may also play into intensification of a relationship. For example, one friend helping the other prepare for a big party on their birthday can increase closeness. However, if one person asks for too many favors or fails to reciprocate favors granted, then the relationship can become unbalanced, which could result in a transition to another stage, such as differentiating.
Other signs of the intensifying stage include creation of nicknames, inside jokes, and personal idioms; increased use of we and our; increased communication about each other’s identities (e.g., “My friends all think you are really laid back and easy to get along with”); and a loosening of typical restrictions on possessions and personal space (e.g., you have a key to your best friend’s apartment and can hang out there if your roommate is getting on your nerves). Navigating the changing boundaries between individuals in this stage can be tricky, which can lead to conflict or uncertainty about the relationship’s future as new expectations for relationships develop. Successfully managing this increasing closeness can lead to relational integration.
