back stabbed

A toxic relationship is like a bad investment
I put in so much and got nothing in return
But heartache and heartbreak 
Even my family was telling me I made a mistake
I just mistook fake for fate
Swear I never seen this coming, you played your role well
Left no traces of deceit but part of the blame is on me
Because I fell back never even checked your phone or wondered who you were talking to
Them nights you said you were working late then came home so happy
Thought you was happy to see but it was someone else making you smile
Still ain't get no closure, maintaining my composure
I could easily expose but I like being the bigger person
Even though it hurts how you had the audacity to not tell me in person
I at least deserve that much but I was just good for a crutch
Now that I'm down on my luck whos there to pick me up.
