Confused

My boyfriend and I have been together 6 years we have a 4 year old boy together. We have been through a lot during the 4 years.

He is emotionally abusive and thinks that another child will fix all of our problems. For the past year we have been on the verge of separating but we have a lease that is not up until July. So... am I wrong for not wanting another child? I track my ovulation and try my best to stay away during that time. Every time we have sex I try to push all the nut out as soon as we’re done and he thinks that I cannot get pregnant because something “is really wrong with me”. I have been to my doctor and she says that I am completely fine and shouldn’t be pressured into having another child. I do want another but not like this.

I love him so much but I just don’t think I can continue with this how it is. I make the most of the money and he does not help at all around the house. I still make his lunch to this day. I just feel lost..

Please need some positive advise.. help me!!
