Whatever happened to "ask for what you want"? Why not tell your son that you are Dad to him and not Kevin? I certainly would have told my kids that if they had called me Beth. Maybe he needs to hear you say that and possibly he NEEDS to know that you are fighting for him. Don't assume how they feel kev 'cause that's a huge mistake!
The other thing that you mentioned about people saying that their step Dad was more of a Father to them. Well I've heard people say that as well, but I've only heard that from people whose bio Dad walked out of their lives. I don't ever remember anybody saying such a thing when they had a loving, present Dad.
Oh and how about you TELL your ex that you would like a copy of your sons practice and game schedule? You shouldn't need to ask if you could go to his practice. If you can't get it from her, find out who the coach is and ask to have a copy sent to your home. You know kev, in the future and considering how uncooperative you ex has been, you may need to do this with everything from sports to school. Besides, don't you think that showing up to see your son practice would send him the message that Dad is interested and present? I bet he would be thrilled to have to you there!
Think out of the box Kev. You are dealing with a very selfish and controlling woman. Don't let her brainwash these kids into thinking that you are "weekend Dad" or just Kevin!
You know I love you so you know I'm not being critcal. It just makes me so angry to see her still pulling this crap!
