Am i wrong?

That is wrong... his gf needs to get a life... if she can't accept u and him being freinds, then I guess she's not going to be good of a gf to him... that's step 1 in controling his life. Step 2 would be maybe she will make him stop talking to all of his friends and go shopping with her. She's taking over his life little by little... so try to stop it.
