Is he leaving me

Me boyfriend seems so off with me I don’t know what to do we’ve planned to have a baby and have been trying for months and now he’s acting strange, hardly heard off him yesterday and today he’s talked a bit but when Iv asked if he’s calling he just says if I have too then doesn’t answer me for the rest of the day 🤷🏽‍♀️🤦🏽‍♀️ this is so unlike him I feel awful I don’t know what to do
