Will my kids mom ever come back to me?

Me and my kids mom broke up back in april. We have 2 kids and been together for 5 yrs. 1st love 1 st all. She cheated on me for her ex best friend kids dad. I think is weird. Lmao. Their both lazy no job no type of money cominh their way. He 28 and drinks constantly and she's 21. Well I have a new girl too. But when I ask my kids my does she miss n love me still, she says no I dnt love you no more or miss you, she moved on and happy. Will they last? Or will she ever come back to me? Yes I still do miss her.
