All humans are deceitful, therefore, I would take being befriended out of obligation because it is easier to predict and understand.

If somebody wanted something from me, such as money, social contacts, knowledge, or anything else, at least I am assured that as long as I continue to provide them with what they want, they wouldn't reject me. Knowing this gives me a degree of power and influence over the other person because I know that they need me. They need what I can provide and it would be in their best interest to continue to please me in return as long as I can provide. Also knowing that they're in my life to fulfill a specific purpose helps me prepare myself mentally for the time that I eventually outlive my usefulness, that way, at least I can avoid being hurt by the rejection or betrayal.

Having a friend and relationship for any other reason is confusing and difficult for me since I have low emotional intelligence and a low capacity for empathy. I can't be assured that that person won't betray me and I have difficulties making people happy due to how difficult people in general are for me to understand, therefore, being a resource is easier for me to understand and deal with.
