Need advice, I’m so depressed 😔

Hello everyone, I’ve been in a relationship going on 7 years.. we’ve been engaged but I broke it off.. I really need some advice ladies 😔 I know I need to leave this man alone but it’s SOO HARD , he told me two days ago he knows he has a problem ( he cheats ) , but he doesn’t wanna lose me... but I know I’ve been thru so much & I need to let him go but I love him so much.. but I can’t go thru another heartbreak.. I seen in his phone this morning him trying to get to know another woman but somehow I’m still here hoping one day he changes 😔😔😭 I pray & pray so much to god to please help me get over him but it doesn’t seem to work.. has anyone been thru the same... please don’t judge me I’m just deep in love & don’t know where to turn 😔😔😔😔
