I cried for a few days and got over it, but I couldn't imagine how I'd have coped without Bella in my late teens and early 20s. We have to put in a lot of work, and the other person has an uphill battle to understand us. We don't know why you need so much attention, or physical contact, or endless listening to problems. If we care enough though, we will try to understand and put the work in.
My little sister took the stance that exclusivity and commitment were the same.
If I'm in an exclusive relationship, I can lie on the couch while she does stuff with her family.
If I'm committed, I'm doing that stuff with her family.
Our theory on commitment was that it evolves slowly, long after exclusivity.
Essentially, commitment (in our guy opinion) is a juiced-up exclusive relationship.
