HOW CAN YOU SHOW SOMEBODY YOU ARE REALLY TRYING TO CHANGE 😔

How can i show him after i have left him down so many times after the relationship ended because of me i was stupid i was retarded that’s the truth i had everything and i let him down now he doesn’t want anything I’ve begged him I’ve cried to him i have a daughter with this boy

My actions have made my babygirl suffer because the pain she feels when her daddy leaves sometimes she even wakes up saying daddy i can’t imagine another girl carrying my daughter or being part of her life i really truly love him and All my heart desires is One only One last Chance to make everything right

I know he still loves me because he tells me he does but that he just can’t because he tried but i don’t know man i still have hope
