I get it. My aexbf boyfriend treated me like crap too at times. Our head tells us no... Don't go back....but our heart is weak because we know what they are capable of and what we once loved so dearly. We accept the love that we think we deserve. Work on YOU and you will most likely find yourself realizing you don't need your exbf in your life anymore and that you deserve so much better. Give it time, you will look back and feel so much better in the longer run without him. Hugs!
