feeling unwanted

It's been 2 years and 2 months and still no luck getting pregnant, all the fertility results came back fine but still nothing.. I have given up on using the fertility monitor and downloaded a fertility calender ap instead to keep track of things.
The last couple of weeks though I have been depressed and resentful. My husband is a business owner and I have been helping him out in the office when ever I can doing simple jobs like filing papers and doing pick ups at other businesses he deals with. Last week he hired a 'secretary' to do all his paper work for him and basically take over the small jobs I was doing. It wouldn't be so bad but since it's a home based business and all of these new employees are coming to the house to use the washroom I feel like I am on display as the useless person who can't even get her husband to hire her and if the house isn't spotless all day everyday I feel like a failure there too. Meanwhile I am trying to start up my own business from home as a child photographer but I have these people walking into my house whenever they feel the need and it's just not going to work when I have clients who need my full attention.
  I just really feel like I don't matter and it ticks me off when my husband comes in at night bragging about how well his new secretary is doing (and no I am not worried that he may be having an affair with her cause her husband also works for us.)
