Should i leave, is he cheating on me?

So while i take care of the kids, 2 under the age of 3, and the house, all my husband does is stay in our room, and touch his phone. Like 24/7.

Yesterday he began ranting to me about how i never give him any attention. And how im always in the living room with the kids, and when theyre not crying or anything, i just sit like a dumbass. He said that if any man lives with me, they would cheat on me, cause i never give them any attention. He said he does the things he do, cause i never give him attention, and he feels like he doesnt exist to me.

I told him i have things to take care of, like the kids, and house, etc. With the house so big, I dont want to just stay in our little room. The kids need to explore around too, they dont want to stay in our room 24/7 either. I said all this to him, and he doesnt care. He still said to me that i need to give him attention, or he will cheat on me, and if he does, i have to see why, and i cant be jealous when i never show him any love or attention.
