You simply ask him about it. Truth accompanied with humility is what keeps love between two people strong. And if he told you one thing yet you know without a doubt he is lying, take his word on it and check your sources. Sometimes the most "credible" tips come from the most incredible people.
Confront Him with the problem and if he does not, in your opinion, honestly answer, then you should probably find a boyfriend that doesn't lie.
Catch him in his lie, he wont know that you know so dont confrot him just get him to tell you about the lie him self, almost trick him. Trust me it will work
it's not like she's having sex with him.... it's just a touch everyone touches each other. if she continues to touch your boyfriend confront her about it nicely
I would confront the girl or warn your boyfriend
you should confront the person right away and tell them you are sorry
It's not helpful or healthy to assume that your boyfriend would lie about specific questions. Building trust in a relationship involves open communication, honesty, and understanding. If you have concerns about honesty in your relationship, having an honest and open conversation with your boyfriend is the best approach.
about what?
you could try acting natural and not flirt with him.
Just confront him about it in a calmly matter
You Dont! because if you have to ie to your boyfriend then there is no point being with him.
Telling you how to lie about your boyfriend is impossible, telling lies without our help is possible but if the truth comes up, that will be the hard part.
Confront her, wait, or move on.
