Want serious opinions

So I found out my boyfriend of almost 3 years was cheating on a fake Snapchat !!! I kicked him out and he’s been blowing up my phone wanting me to take him back ! I just don’t think I can because I’ll just question after... so what’s all’s honest opinions? Have y’all ever had a guy blowing your phone up saying he’s sorry and he’ll do anything to change and make it up and him just cheat again ????
