you were with this girl for a big part of your young adult life, and that made an impact on you.
it can seem like she is part of what makes you, you.
but you are you all on your own.
maybe you are feeling insecure because it feels like you are losing a part of yourself...
well you arent.
youre still growing.
29 isnt all that old but it isnt all that young either.
you need to come to grips with this now, so that you can move on and embrace your life.
