is it right for ur boyfriend to lie to u and say hes sumwhere else when hes with another girl

no.
1 he lied. who knows how many times hes lied to u before and when he might lie again.
2 if u kn ow the girl and shes just a friend hàng đầu, đầu trang that guy then i guess thats ok. but if ur not sure something else might be going on. it might be what u want to hear but its the truth

Absolutlty NOT.... If he lied to bạn that shows bạn that his unfaithful plus may be cheating.. bạn should ask him why he lied and if he acts all funny then dump him his not worth sticking around with Good Luck

HELL NOOOOOOOOOOOO!!!! its time for bạn to di chuyển on now. if they do it once it WILL happen again trust me.

no its not okay. but may i know the situation here, why did he lie to you? who's the girl? and why are bạn so confused when the answer is so obvious?
