Mine (in order of importance/ personal preference) are:
Quality Time
(I value quality conversation and receiving periods of undivided attention above all else in a relationship honestly, since I often feel that time spent together with loved ones will only serve to strengthen our bonds and maintain that sense of closeness between us; the depth, or at least overall flow, of my conversations with someone, whether over similar hobbies or values, also help me assess the amount of chemistry I may have with them and how much ease or openness I can experience in our relationship. Based upon personal experience, it is very hurtful for me whenever a person appears disinterested or apathetic toward what I have to say and constantly refuses to spend time alone with me. It is also good to mention that I often prefer and do much better with one on one interactions with people, rather than be surrounding by several of them in a very boisterous public setting).
Physical Touch
(I need physical affection from the people I'm closest too, since I feel that physical touch in any form shows that barriers have been broken and that there is a deeper level of openness and trust among yourself and another person. A constant lack of affection might instead make me feel awkward or confused as I struggle to figure how to deepen my bond with said person, interpreting the lack of affection as aloofness or disinterest. I am not saying that I crave this to the extent of say, the sappiness of the Full House characters who thrived upon this, but rather that I at least need at least some trace of this from my loved ones in daily life to feel appreciated).
Acts of Service
(It is flattering and heartwarming to me when a person offers unsolicited help or assistance to you with something, since it shows that they are considerate of your well being and feelings and care enough to want to accomplish a task or help you with a chore out of love).
Words of Affirmation
(Honestly, I do enjoy words of affirmation more than this list may imply, yet I sometimes feel that continuous compliments and flattering from others can border on insincerity, particularly based upon the person's speaking tone and body language, or at least, from whom you're receiving the compliment to begin with.I may feel genuinely loved if I received affirming words from my mother or a very close friend perhaps, knowing that they are most likely honest in what they're saying, but wouldn't feel as appreciated if it came from a classmate I hardly knew or someone who has a reputation of being overly nice to everyone).
Gift Giving
(Although it may feel nice to receive gifts unexpectedly from a loved one, I've never really interpreted it as a symbol of love or affection, since the act itself may feel rather empty once the gift is received from someone who isn't truly attentive or genuinely caring towards you. I am also aware of this because this is precisely what i have experienced with my own father, who has continuously been absent from my life for several years, yet tries to compensate for this absence with gifts).
