Thanks for the reply.....

I have just one TV at home and they are using it anytime they are there to play Wii. Frankly, it's too much for me. I can't get relaxed at my home.
He moved in with his mother, because he wanted to save money (and he makes good money since he's a lawyer). His mom is a real monster and she was rude to me, so since then he brings the kids over to my home when he has them during weekends. and of course, my house is way better and bigger than his mom.
He used to bring them over during the week but we had issues and he doesn't bring them any more, they go to his mom's home!
He got separated three years ago and I didn't know him at that time. His separation is nothing to do with me and he had lots of girlfriends in between!!!
I'm so hurt particularly by the fact that he was so mean to me telling me that I have no rights to tell the kid to not play wii!!!
However, later on he apologized, but honesty, I think that's what he thinks.
I feel outsider and he confirmed it while he was angry!
I don't want to have the kids next time. I'm not here to baby sit them, provide them house and shower and swimming pool and then not being appreciated!

I'm still so angry!

And I didn't want the kid to use the TV. They had it enough. The whole weekend and it was time to sleep. Frankly, if they were my kids, it would have been the same.
