Step dad supporting home

Kody
To start.. This is my 1st post on here.. I'm just up in arms and have searched the Internet but I can't find any comparable situations.. My son was 6 when I got pregnant and I left my husband due to his drug addiction (he soon after went to his 3rd rehab out of state). I had enough after finding out about heroin at 8 weeks along. I spent my entire pregnancy with my little guy by my side and was happy with my decision. Our (my then 6 year old and I's) baby was born I honestly never though I would be in a relationship until they were 18 lol.. I met a great man when my baby was 3 months old 😳 we moved in together this last October (just about a year after dating). He has an excellent job and has been the sole male influence for both boys. I work from home as a NEW freight broker and bring in just enough to cover my car payment. He said from the beginning that's all that he expected. I have always supported my household with no family support (financially) and haven't had a dime of child support for almost 2 years. 
Just recently my boyfriend has been coming home and doing NOTHING. No help with laundry, no dishes, no cleanup... Our house is perfect when he comes home. Laundry is done, not a dish to be seen and dinner is starting when he gets home. It's been weighing on me that maybe I have done 'too much' (he gets a packed lunch EVERY morning, coffee, etc). But then on the other hand he's supporting my 1 and (now) 7 year old and although he treats them as his own he's never had children. Do I keep taking care of everything and having him come home to put his feel up or hang with his friends in the garage or do I say something??
