Theres a difference between taking his father role seriously and looking forward to it, and being controling and possessive over baby ...i know alot of ppl that say their goin to do this and that when bby comes(parenting and disciplining) but when the time comes are complete opposite...hopfuly he turns out to be a great daddy, and if not well you always have differnt options of what you can do...just always put bby first amd trust your instincts
I think your just gona have to deal with it. hes the kids dad whether u like it or not. if hes not harming the baby and being responsible then theres not much u can do
