Bf troubles

So since being pregnant me and my bf have been having major troubles. He tries to argue with me 24/7...he's procrastinating on everything baby wise and I'm pretty much 5mths and time is ticking..he doesn't touch my tummy or act like he's really interested but he's the one who wanted this baby more than I did and now that the baby is coming he's done a complete turn around. He acts like he's the one pregnant smh..has anyone else had this issue??
