how do you know

how do you know
how do you know that you are over someone
if you still think about them every now and then
if you wonder if their life is ok
if you ask yourself if you ever cross their mind
if it still makes you sad that the two of you didnt make it
how can you say
how can you say that you no longer love them
if seeing them with someone else still hurts
if you look at their tweets just to see whats going on in their life
if you still havent gotten rid of his clothes that you have
are the other feelings
feelings you have for other people
are they fake
do they exist
can they exist
if you still have these random thoughts of the ex
if sometimes you wonder what if
can you truly fall in love with someone else
and tell them you want to be with them forever
or would it all be a lie
am i living a lie because this is true about me
or am i just real
is it bad to think about your past
no matter what capacity it is in your mind
or is it natural
just because i think about someone sometimes
doesnt mean that someone else isnt on my mind all the time
but, how do you know
