I sent a text stating were done if you carnt be arsed the betha can I.x. It was meant for my sister but sent it to my chap by mistake and now he won't answer any of my texts or telephone calls. Apologised loads but nothing!!

So if it wasn't that bad of a text, wasn't meant for him, you apologized and he won't answer, then is he really worth dating in the first place?

Maybe he couldn't understand what you were saying.

Just wondering how that happened- and maybe your friend is too.
If it was a reply it wouldn't be likely to happen. If a new message you usually have the other person's name already in your phone and you match or select the person from your contacts. I am a klutz at texting and emailing but I have never done anything like that. I sent a text to the wrong person once but that was because my friend's work cell phone number had changed and I didn't know it. Maybe if you give your friend a plausible explanation of how it happened, you might have a better chance at convincing him.
What was the actual statement meaning in that text? Could he be reasonably be expected to believe that it was a likely question you would be asking your sister?
"I sent a text stating were done if you carnt be arsed the betha can I. " Give us a translation.

Yes, I agree, he may have trouble knowing what you are saying, ( I know I am) but how about going and seeing him in person and talking.

Maybe a face to face is what you need.
