why do men do this?

Have just broken up with my partner - must be xmas - and he has come back saying I will change and I love you. But in the same breath bags me out about the bad financial decision he thinks I made by buying a block to build on and that if he and I are to have a future I need to do something about the dust and cat hair in my house and discipline my kids better. What the?? Isnt love about accepting the other person and supporting them? And how can you bag someone and in the same breath say you love them? I don't understand how blokes minds work. This year many families in Kinglake are facing a Christmas without loved ones at the table and he is on at me about cat hair. hmmm.
