It would depend on what the significance was. Why are you so certain he lied about it? It really is a loaded question but the answer is within yourself. If you feel you can not trust this person then deep down you know the reason. If you a certain he lied then why would you want to be with him anyways. A person who lies can never tell the truth.
if you know for sure that he is talking to his ex and he is lying to you about it confront him. if he doesn't admit to it and is being defensive then you need to ask yourself if you want to be with someone like that. but if you don't know for sure, you can't accuse him. do some research first. it would be bad if you accused him of this and he really wasn't doing it.
NO if he was a lying boyfriend that's not going to go away
contact him
Have them sit down and talk to you face to face.
It is obvious you are still in love with your ex boyfriend and hoping to get back together with him or it is wishful thinking that he will contact you and therefore he is on your mind a great deal so it is normal to dream that your ex boyfriend is trying to contact you. If he does not have a girlfriend then out of curiosity contact him and see if he will meet you somewhere. Take the risk.
He probably doesn't like eye contact or he is lying.
Because he doesn't want you to contact him.
"He is your ex boyfriend" is correct.If you were to say "he was your ex boyfriend" it would suggest that he is no longer your ex.
Nothing - carry on as normal and live your life happily. He is your ex and he was that for a reason.
because they feel guilty for hurting your feelings
i mean, if he's your ex-boyfriend he's your EX-boyfriend. that means...boyfriend.
You will need to contact the police or the courts to get restraining order against an ex in Riverside, CA.
Your question is not very clear. Why in the first place are you trying to stir up trouble with his ex-girlfriend? All this does, is leads to arguments with your boyfriend. Why bring on more problems for yourself and your boyfriend. His EX is an EX for a reason. Do you want to be the next EX? That girl called back because she thought her ex-boyfriend is still interested in her. That is why she called back. Don't be dumb. Leave the ex-girlfriend alone. You don't want your boyfriend to be talking to her and having any contact with his ex. All you are doing is bringing up old memories for him. You want him to concentrate on you and not her. Be smart and concentrate on the two of yous relationship. If you feel he is contacting his ex-girlfriend, then confront him about it. If he lies and if you know he is lying for sure, you cannot trust him. One lie will lead into other lies and heartaches. If he truly wants to be with you, he should delete his ex-girlfriend's number from his cell phone. Since he hasn't, this tells me he is still interested in her and does contact her. Be aware. probabily because you texted her from her Ex's phone.
