Sometimes I don't want a baby...

My husband and I have been TTC for a few months, married almost 2 years but I feel like so much has changed since we first got married. DH has no passion or drive, constantly on games or internet and I feel like he's lost touch of what really matters. 
​I've tried talking to him SEVERAL times but nothing has changed. He used to work out every other day, but now all we do is sit & watch tv. 
​I want a baby, but I don't want to be lame and boring parents, or feel alone in parenting while he's in another world.  I want to talk about it but I feel like a broken record, repeating the same thing constantly :(
