I dont mean to sound like confrontational but saying things like it comes with time and nobody is unlovable, sounds like gross generalisation that has no basis in reality whatsoever. There are so many people who lived alone all their lives and not by choice. I caution against being attached to hopeful fantasies as chances it would back fire are tremendously high
It is based on psychology and neurobiology. From a scientific standpoint, love is a phenomenon which involves the limbic system and a plethora of hormones controlled by the pituitary gland. It is extremely crucial for human survival, as it serves a psychological, physical and reproductive function. For example, one of the hormones which gets released in cases of mutual attachment is vasopressin, which plays a key role in regulating plasma osmolality. I do admit that love cannot always 'come with time', as it depends on the person. But, the statement that nobody is unlovable is factual. In most cases, the primary reason as to why we can feel unlovable is due to our own perception and unresolved past trauma. This is reflected through attachment theory, or the theory that the way we perceive emotional affairs (such as love) is based on our caregiver's psychological response towards us in our childhood. Individuals who grew up in negligent households with no emotional support usually develop a dismissive personality, where they underplay the importance of relationships. Those who had unpredictable caregivers commonly display symptoms of high anxiety in their adult lives.
It is true that there have been many people who are in the older bracket, but have yet to find a companion. It is also true that most do not have a choice to do so. But I argue that there are always underlying factors to this. Whether it is the lack of self-confidence or mental health problems, it is in no way the individual's fault. Take a look at Elliot Rodger, the misogynist mass murderer incel. He was fairly attractive and was quite independent. Yet, he never got a girlfriend, which sparked his femicide in 2014. His 'attempts' of finding love included sitting in his car, waiting for someone to approach him. Obviously, this did not work. By watching his YouTube videos, one can immediately notice his inflated ego, as he expects others to naturally be in love with him without any effort from his side. There is an interesting video on the YouTube channel Together TV, which showcases the life of a 40-year-old virgin named Clive. He is a well-off and intelligent individual, yet has never had sex before. He cannot talk to women in a flirty manner, as he does not have the self-esteem to do so.
As we move into a more sex-positive society, we also become ashamed of ourselves and our lives. We seek answers to our exacerbated questions. Why am I alone? Aren't I enough? Is there something wrong with me? Am I just unlovable? All of this pondering can destroy an individual and their ability to connect. This can cause involuntary dismissal of other's care, or just an extremely scarred outlook on attachment and relationships.
Call me a biased, delusional, hopeless romantic, but I do believe that love can change lives. It certainly changed mine, though the person responsible for that is now gone. We were both unstable and severe depression got one of us quicker than the other. Their absence has brought me great pain, yet I am grateful for the comfort and love they gave me.
I am not here to command the way you reason love; we all have our own set of beliefs. I just wanted to share my own take on the subject as a way to comfort a fellow member, the same way that the person whom I loved dearly did when I was suffering from melancholy :)
