Yes. I can empathize with you, Nikki. We all do things that we feel are right at that point in time. Meaning, given the circumstances and situation you took a decision that seemed right for you then. You implemented it and now you are feeling that it is a wrong decision. Perfectly OK. Go with what YOU feel is right at any point in time. Today’s right is tomorrow’s wrong. There is no need to regret it. In life, it is all about the experience. Then it is about learning from the experience. A relationship just does not fail. It simply does not work.

Coming to the second part of your post – there are 2 ways of seeing it:
1) Giving love another chance in your life
2) Remaining single for some time and focusing on yourself – practice self-love, self-compassion, and mindfulness. Focus on your goals and dreams.

I suggest you give it some time before you jump into someone else and lose yourself in the process all over again. Give some time to yourself before you figure out what it is that you want from life.
