Choosing the first would imply that you intend on remaining single your entire life - as every relationship has a chance of ending. Breakups are never fun. However, they give you the opportunity to reflect: What went wrong? What is it that you don't want in a relationship? What is it that you do want?
Have exes. I mean at the moment, if I had the option to go back in time and not date the losers I have, I would take it up. But since don't, I'm still okay with it. It gave me experience and helped me to realize what I do want in a relationship. My boyfriend is not perfect, but I'm lucky to have him and he's a 100% better than all the other jerks I've dated before.
