am I over reacting?

I told my bf I dont would like for him to move out. All he does is play on his phone and when I say all he does its literally all he does from the moment he wakes up to the moment he goes to sleep. hes eating hes on his phone shitting on his phone driving on his phone at work on his phone. this has been going on for about 8 months now. We have a almost 3 year old son and I'm 2 months pregnant. we go on 0 dates and dont even sleep remotely close together. ne never helped me with my son when he was born and he wasnt even that addicted to his phone. when I take my son out we (me and my son) will leave the house and when we get back hours later hes still in the same spot playing on his phone. the rare times I drag him with us hes on his phone the ENTIRE TIME.
