Relationship is hanging by a thread

Emily

Me and my significant other have been having a really hard time like about to break up because of this.. my almost four year old has trouble sleeping in her own bed by herself so I lay down with her until she falls asleep. He says this leaves us with no time at night because he goes to bed early to wake up early so we don’t get much adult time at night if any. I also have a four month old and take care of the house so I’m exhausted by the end of the day. He doesn’t understand I can’t just leave her in there to cry..but I do want more time with him. Idk what to do but we are so close to splitting because he claims I give him no time. He’s mean to me every day and says that’s because I give him no time..Advice?
