Thank you, your 100% correct.
I don't think you should stress yourself over something you cannot control. You should tell him you need to talk in a quite place & express how you feel,if nothing changes then focus your energy & thoughts on the baby. I know it's hard because you had the support from the first dad ;however, every man is different some will not go into daddy mode until the baby is born especially being his first. Don't stress yourself it's going to affect the baby.
