I want my bf to propose and to have a baby but he won’t

I’ve been in my relationship for a year and my bf talks about marriage and stuff and I’m ready to get married and start a family but I’m scared he won’t be supportive. I also have an IUD and kind of want to take it out but don’t want to try other birth control cause I’m ready for a family but am afraid of how he will react to it. Don’t know where to go from here lol
