Self-image is a very tough thing to face, but extremely beneficial nonetheless. Like you, I spent an extended period of time single and sort of wallowing in my self-pity (at first).
But what I took out of that over time was a very mature and developed sense of self, to the point where my more recent relationships were very healthy and supportive (even the ones that didn't last). We eventually realize the bigger picture and are not as concerned with others' approval.
Self-honesty is one of the most brutal and yet insightful acts to indulge in. Kudos to you for focusing on being happy. Thanks for sharing!
Yes, I use the opportunity to get to know myself and have learnt a lot during those tough times. Plus, after a few incidents that lead me to a few self-realization and self-awakening experiences which help me to see the universe in a very deeper point of view and perspectives....:)
