Hi girls i need your advices really

Okay I was with this guy like about 3 years now but broke up last month and we don't talk anymore but I not hurting or something but I am confused between my heart and my mind

For example : my heart says to me okay if he comeback you're gonna say yes But my mind tells me no you shouldn't get back together remember all the pain the crying and everything have done for you while you did your best , so this is just a vision of what happens in my mind all day so i wanna know how just resolve this and who i should follow cause actually even we hade a great relationship but I've stayed lonely a long time while with him and just waiting for him ta call me i mean he's busy all day i hope you understand this and i would appreciate your advises or reviews. Thank you in advance
