Should i break up with my boyfriend?

Okay well my boyfriend and i been back together for 2 weeks now. Before we dated he texted and talked to me a lot. and then when we went back out he stoped talking and answering my texts. I told him about it before and he said hes to busy.. but he was not busy to text me before?? Also he calls this girl his wifey and says he loves her and stuff. i asked him about that too and he said they are just messing around. so what do u think i should do. break up with him or stay with him to see what happens?
