How do you move on when you let the person go and then you regret is later?

.::All guys want is a relation not a R.e.L.a.T.i.O.n.S.h.I.p..::

.:: You say its not over.. What the flip do you mean its not over. It is over.. I am done listening to your f.u.c.k.i.n.g. L.i.e.s. You can't live without her.. Well then go be with her. I don't want you.::

♥Why don't you just get outta my face..
And go back to your other girl..
You love her some much more right..
Well when you want me back, its gonna be to late♥

♥Just get outta me face..
And go back to her..
You left me for that remember..
Well just remember when you want me back.. You L.e.t. M.e G.o.♥

.::You see theres this thing called jealousy.. But to bad when you were trying to make me Jealous and bringing another girl.. Wow it didn't get you anywhere.. But made yourself look stupid.::

♥Since we separated I know you will never find
Another chick like me that's why I stay up on ya mind
I know it's hard for you to hear, but I ain't got the time
I moved on, I moved on
I don't want you now♥

.:: I guess like they say..
You Don't Know What You Got Till Its Gone.::

♥I don't wanna say I still loved you
It hurts me everyday thinkin' about
Who you were kissing not me
I'mma speak the truth
I ain't gon lie
I let you go with all the tears I cried
Thought we was goin' ride♥

..:They say just let go..
They say Ill be alright..
They say hes just a boy..
They say I will get over him..
Well what if I tryed a million times and it don't work..:
