Need help deciding if this is fair...

Do you think it's fair for me to ask my husband to not partake in his fantasy football draft with his friends for the next couple drafts/years? I guess you need to know our situation..But our relationship is something we are working on to get better due to a few lies he has told as well as bad fighting between us. We are trying to focus on bettering our relationship so we can possibly think about starting a family. And when we do have our first child..I want him to focus on him or her and not be so glued to his phone. I feel the football is just in the way. on top of the fact that he is doing college online and should also focus more on that. he hasn't been doing to well with the distraction of fantasy football. help please !!
