My ex-boyfriend and I dated for about 5yrs and I dumped because he was to immature for me. I told him once he grew up a little bit I'd give him a second chance. One year later I bought he had changed but then realized he never would. So now he won't stop talking about me on the Internet and to his friends which makes it hard on me since we go to the same school. He's also textin me so really immature things and I don't know how to get it to stop. Occasionally he'll call me and tell me about his problems and expects me to care after what he's said behind my back. Please help ASAP!!

I know it sound like effort, but with guys you have to repeat yourself over and over to them. Explain to him again that your maturity levels are just too different and although you thought he had changed that he had'nt and therefore you don't want any or little contact with him as you don't want to make some one change themselves just to please yourself, but you also don't enjoy his company. You will have to explain this too him a few more times for him to finally get the message but adventually he will understand and either grow up or leave you alone.
Hope this helped :)

Tell him you don't like him.or ask him to stop.

Tell him where to go , and how to be there . : p
