You dont force people to do anything.
How well does it work when you feel forced?
Give opportinities to be involved, open the door to options, dont subject your daughter to neativity.
If you give plenty of opportinities for your ex to be involved, it is up to him to make the choice. Dont complain about his choices, just go forward.
There may be special events, thes may be an easier fit for him. In a public type setting, limited time to be available, and not in his court of responsibility. (Like gong to a sporting event or something. He can be there, but not in charge of how the venue is presented, and the time of the event is structured so he wont fell like he has to cut something short)
Do not complain about him in fornt of your daughter, even though you want her to understand how you feel. Try to say you dont like how somethng is done, not that you dont like what he did.
Stay focused on your daughter, keep a clear mind, and go forward.
