Can DHS deny my children and I food stamps because of my boyfriends income?

I have a boyfriend. I am a mom of two and I own a house. I see him regularly. He has his own place but spends most of his time with me. He doesn't have this as a legal address and still pays bills on his own room with a friend and a storage unit for his guy stuff (motorcycle, tools, stereo and furnishings etc.). I have to admit I feel safer when he is here but he doesn't give me his check. We don't have that kind of relationship. He helps me with guy stuff and I feel protected. He fixes my car and cuts the grass and does the snow. I get no child support. I have income from my small company and I get $250.00 for food stamps. I have been denied food stamps and I am afraid they will take my health insurance. Can they claim his income? They say I have too many assets?
