I did the same for my daughter with the understanding that there would be no more calls to the ex. Well that lasted approximately one month. Then she started making excuses, like it was his daughter that borrowed the phone and called her dad, etc. It just caused a lot of friction and she ended up back with the abf and I ended up losing 400 to get the phone back on. So do what you want, but if he calls the gf then you really can't be mad because you gave him the means to do it. Hugs, Marle
