So, I am a mid 20s man. When I nothing that catches the eye in an attractive or in an unattractive way. The neighbourhood I rent in which is close to my office is mostly populated by young couples. I have never been in a relationship, so I never have co-lived with someone else. I want to know what is like and I envy them so much, when I see them going to work together or drinking coffee on their terraces on a Sunday morning. I feel envy, I feel like I am a screwing up psychologically. The reason why I feel this way is I have started a PhD that will finish in 2026 and I don't think I want to start a relationship until then. So I am stuck in a scenario where I envy people yet I know it is not yet the time to put effort to be like them. How to stop envying them? After I finish my PhD I will try to date as much as I can but if I am not successful I will still feel bad I am single and envy. So how to stop?
