Wolfman moving forward

[Wolfman]

Ex is at it again. My 11 year old son was begging me to play tackle football. I had some reservations about it. I played college and semi pro. I know a lot about football. When I found out I could coach my son I gave him the ok. He was super excited, he couldn’t wait to play. He was cheering in my car when I told him he could play!! I said you just have to ask your mom. I spoke to him last night and he said his mom said no. I asked why? He said because she said it’s not safe. I said I would be coaching. He said I know but mom said it’s not safe. I said that’s ok that mom said no, if you still want to play I can sign you up.
Side note, the only reason I have to get his moms permission is because of the expense. We would split it, if she says no and I decide to put him in the expense is on me. Just wanted to clear that up.
He said no I don’t want to play now. I said what do you mean? You were begging me to play, now you don’t? He said he is already doing flag. I told my son, open your eyes your mom doesn’t want you to play because it would be more time with me. Why else would it be ok the following year when he is on the school team and I can’t coach. She did the same thing with baseball. He wanted to play and convinced him he didn’t want to. I am most mad because he said he doesn’t want to play now when he was begging me for months. Now he doesn’t want to play because his mom said no. This is just so wrong!!!
