The reason I feel unwanted is because in the past I have found out several times that after hanging out with someone or a group of people, I was never wanted. And it happened with several different people, not just one. Someone befriended me out of pity, a group of people invited me somewhere out of politeness and a couple times I was even invited to a graduation party only to find out later I was never wanted there. Thankfully I was not there long. One person actually kept on asking me when I was going to leave the party only after five minutes of me being there. I was there for a total of ten or fifteen minutes then got the hint and left. And now Also I have been used a lot since I used to not be as assertive but I am way more assertive now and avoid being used a lot more now. Being used is not my biggest worry since I am more assertive, it is people befriending me out of pity or obligation that worry me.
