I had to accept I would be single forever when I was in an controlling relationship and my partner reminded me that I was ugly and lucky to be in a relationship at all. I really wanted to be in a relationship and has trouble attracting anyone who wanted one with me for years before that one. I feel like I put out a desperate vibe that repelled a lot of potentially good partners and attracted unhealthy ones who wanted to take advantage of that.

You deserve a healthy relationship, and it's okay to want one! But accepting that you might not get it now or soon helps you live your current life to the best and avoid people who want to rob us of a healthy relationship.
