I'm in your thread about babyproofing your house. Seemed like your SO was treating you like crap, so I checked your other topics and found this.
Honestly, girl...you need to get out. It's not healthy for you OR your daughter. Even though he's not physically abusing you (at least you haven't said he was), you could call or go to some sort of office that's for women and young children, I'm sure. Depending on how much you make, you should be able to get at least some
assistance in rent and/or food. That will help you get on your own two feet, financially. If your SO tries to harm you or scares you when you move, call the police immediately and file a report. If you fear for your life, they can make up a restraining order. If he ever threatens to take your daughter from you, that's grounds for a restraining order for her as well (my co-worker just got one from her ex because he said, "you better keep eyes on Mia at all times"...they don't play when someone threatens a kid).
There are resources to help you. It sounds like your little one is unhappy and is picking up on how your SO treats you. You're not in a healthy relationship and it's affecting your daughter. Don't hold onto something that was good if it's been bad for so long...especially with a prick like that. He's not going to change, so don't expect him to. If you leave and he actually does change, then you can consider a second chance for him, but at this point, I'd say no go with continuing that relationship.
If he is abusing you (and you just don't want to say it here), you can go here: http://mutualground.org/
They're located in Aurora, IL and their FAQ page states that emotional abuse is domestic violence and should not be tolerated. It also states, "Domestic violence is a pattern of abusive controlling behaviors..."
