So confused

Mehgan
My husband and i have been together for 2yrs and we have a 9month old and I'm 5 months with our next one. In the past i cheated and we worked things out. But he will still bring it up from time to time. I just ignore it, he now sleeps on the couch its been 4 months that he has been there he said the reason is because i don't show him affection. But i work 3 jobs and im tired. I try to but he still want to sleep on the couch.
