how was your relationship before you got married? I'm sure there's a reason why she's like that, and i'm positive a good counselor would help, but only if she's willing to work on the relationship herself...
what other things does she complain about? obviously not that you don't do anything in the house (wow i wish my husband was that active in the household), but other things... maybe you used to do things that made her happy before you were married and now you're not doing that anymore (which is normal) and she misses that...
you said you know she loves you, so somehow she's showing you that, maybe you should try to show her that you love her in the same way she shows you. everyone has different thing that makes them feel loved, for me it's spending quality time with my husband, but he feels loved when i cook for him and touch him... everyone's different, maybe part of the problem lays there... a great book that discusses that is "the 5 love languages" ...i really hope things will get better!!
