I'm so confused...

My boyfriend and I have been together for 9 months now and it has not been great these 9 months yes we have had good and bad days just like anyone but one thing that gets me is that he has been less romantic less affectionate and I just don't know what to do anymore we argue all the time now and when I sit down and talk to him he has this look on his face like fuck here we go again I love him and I'm tired I tell him what's wrong and how he's changed and all he tells me is well people change and that's it.So should I just except the change? I'm I crazy here or something?.we talked for about an hour last night and after all that the last thing he had to say was stop wearing your feelings on your sleves....
