Part of growing up is having relationships and losing them,
through some faults of others or ours, either entirely or partly.
But we need to hopefully learn from each of those previous
relationships and hope we don't repeat the same mistakes in future
relationships. But at the same time we ought not to be cynical or
having the revengeful mindset in future relationships.
Live life because of yourself. There is no need to prove anything
to your ex. It's your life.
Looking for someone new? Sometimes, love is strange, the more you
look for it, the more elusive it is. Don't be in a hurry to seek
out that new love. It will seek you out in due time.
As others have said before, it's time you get into the big pool
again. Who doesn't have scars? Not many of us get to settle with
our first love. Don't lose faith.
