Do I have a right to be angry?

My boyfriend kept texting his ex… It upset me so I asked him to stop. He wrote a long messsge to her telling her how he was never going to speak to her again and then blocked her number in front of me.
Today, however, he confessed that he had been texting her behind my back and had had her number saved in his phone under a different name all along. He claims he had only been texting her to see if she was aright (because she apparently had recently been dumped by a different guy.) I however, am quite upset by this. I don't text any of my ex's, or talk to them in any way, so why should he? He claims that it is "none of my business" who he texts. I know most of his friends are female and that is fine; I don't care about that, I just don't think he should be texting his ex? (Who lives in another city, who he's never met in person, only online, and who cheated on him constantly.) Also, he's 21 and she's 16… He works and she's in high school. I'm 18! Closer to his age, who would never cheat and who he's met in person! Wtf should I do?

Also, I knew the passcode to his iphone but when I went to check his phone (just to see what he had really been saying to her) he had changed it. Recently. After he told me that he had been talking to her again. I'm not really sure what to think now? I need advice.

I basically think it comes down to trust. If you can't trust your boyfriend to be able to speak to other girls and do they right thing then you've got problems in your relationship. Who his ex is doesn't matter, whether he met her in another city or online etc; it doesn't matter! What matters is that you need to trust your boyfriend. I would think of his ex as just another girl - his feelings for her are obviously gone or he would be with her. Also, the more you try and impose rules and regulations about who your boyfriend can and can't text, then the more you are going to drive him away. If he has never done anything to betray your trust then I wouldn't worry too much.

You have the right to be angry at him, he's not/wasn't being totally honest with you in the relationship. You should try to talk to his ex or maybe ask him why he changed his passcode if he had nothing to hide.

Still in love with his ex

The fact that hes been texting her behind your back, has been lying to you and ignoring your warning. You have every right to be angry. He obviously still cares about her and he doesn't even worry much about hurting your feelings… I think you deserve someone better than him.
