Sharing a bed in our apartment?

Virtually all pediatricians agree that cosleeping with children isn't a good idea. You seem very upset about your own feelings of abandonment when really this should be an issue of what's best for your kid. Yes, we'd all prefer having a big bed to ourselves but in limited spaces that don't allow for it it's just not possible. You probably shouldn't have another child until you can get yourselves into a bigger domicile. 

dont have more kids......she is on her way out

I'm now getting divorce but this was the first sign of marital issues for me. Don't make the same mistake as me, get help, get out or prepare for a long slippery slope. If it really is a bed size issue get a King Size one, or offer to take turns sleeping with baby.

With a wife like this your idea is correct .Give up on the marriage avoid fighting .

You say her father went back to China, so is she Chinese? Are you Chinese? I'm not familiar with Chinese culture but according to a 2010 study called "Co-sleeping and children's sleep in China" it says:  

"Sleeping in the same bed as their parents is very common in young Chinese children, being present in up to 79% of pre-school children and 53% of school-aged children. It is socially acceptable to Chinese parents as a natural part of the child-rearing process." 

So this might be absolutely normal behavior, to her, and the way she was raised. She might think this is the way to be a good mother. Have you talked to her about her childhood? 

Maybe she really does like having a big bed all to herself. Maybe you are difficult to sleep peacefully with. Some people snore, toss and turn, talk in their sleep, etc. Or maybe she does these things and doesn't want to disturb you? 

If you are on the verge of giving up on the marriage, then you really need to have a serious heart-to-heart talk and try to reach an understanding and a compromise, or go to marriage counseling. 

Would it matter if we had a clue how old your son is? My Mom and Dad had 5 children and I know none of us slept between our parents as babies or any other time. Not that they were dangerously deep in the throws of affection but because it just wasn't done. Then again, a "Double" was the largest mattress available. 

I would suggest that you focus your caring listening loving attributes on what has happened between you and your wife that she would prefer the baby's snuggles. It is nature's way that Mommy focuses on Baby but that's unlikely the reason she's so withdrawn from you. More likely the combo of at least those two. 

Kids who can climb up on the bed need to be in their own bed. 

You can do anything you want. But given your wife’s history of abusive behavior and irrational rages (based on your other questions), I don’t know why you’d want to provoke her. I also don’t understand why you would even consider having another baby with this woman or why you haven’t divorced her by now.

(Playing along that this is real and you aren’t a troll)

What marriage?  You mean one where each of you pledge to love and honour each other?  Your first step is marriage guidance.  To get the issue out into the open. After that it depends on what surfaces.

Time to go see a lawyer, and get the divorce now, get it over with already. In time you will get sick of her crap, and you will leave her,

That sounds awful. Did you have a question, or just the venting? I mean I'm sympathetic (although I don't know why you married her), but I don't know what you're asking us.
