I Don't Understand

I don't understand
How on the same day you say that you love me you out with that man
You ruined our plan of being together forever and finally raising a fam
I made you leave
I couldn't put up with your problems no more they were bigger than me
I should be free
But I can't stop thinking about how the love of my life would go cheat
I hate myself that I miss you
I hate the fact that you're gone
I hate the way you think it's ok because of your pain you are treating me wrong
I know that you got your issues
I know it's harder to move on
I know the way that you cope with your pain is by hurting the ones that you do want
I knew that this would come to the end
We gotta part ways there no way we be friends
Wish that I could I can't make amends
How can you live with the shit that you did
You cut me slow then tell me don't go
But how you except me to let you come home
When all that you did was bringing me low
You talk about love but you never did show
Cause love is not cheating and lying
Or making the other one feel they like dying lt's bigger than that
All of the time I was trying to keep you from flying but I'm never taking you back
Wish that I never was fighting for someone confined in the shit that keep them in past
I thought that I saw the lighting and soon l'd be finding but I was so wrong about that
I was wrong about a lotta things in the late nights when I can't sleep
l'm in my bed and l'm all alone you not here but you in my dreams
These thoughts that I still think I can't believe I had to leave
I'll never know where I'mma go but there's no chance that you with me
There's a chance you change ways and you finnally getting better
You will come back in my life and tell me we could beforever
I will think back to this time and go remember I said never
Gonna let you in my life again there's no way well be together
