Love triangle gone wild?

ive been with my daughters dad for 4 yrs and ive been falling out of love with him for the past two. that happened cuz he was messing around on me. well in september i started fallin for another guy and i left her dad alone. ever since he has been asking me to get back with him n saying that he would change. well a couple of days ago i suddenly had a change of heart and now he is talking to sm other chick n he asks as if he doesnt want me back but last wk he was still wanting me. well i want him back but now he is startinshould i stig to play like he dont feel the same. we are still messing around n i am still talking to the other guy. my question is should i keep trying to pursue him or shoud i just move on n stay with the other guy.
