help me write a paragraph telling other people boring it is been a spare wheel in other people’s relationship while you don’t know

Being a spare wheel in someone else's relationship can be immensely boring and frustrating. It's like being on the outside looking in, never fully included or part of the intimate moments and conversations that couples share. You constantly feel like a third wheel, unwanted and unnecessary. It's a lonely and isolating position to be in, always feeling like you're just there to fill a void or pass the time until the couple decides they no longer need you around. Being the spare wheel is not only dull, but it can also be emotionally draining and damaging to one's self-esteem. It's a situation that no one wants to find themselves in, yet many of us have experienced at some point in our lives.
