Together 18 years, married almost 10. I (37M) am really struggling to come to terms with losing my (35f) wife.

Whats worse is that i'm to blame.

We have 2 boys who are 15 and 10. We just built our first home and we have a rather large mortgage. Wife has been bugging me for 12 months to have another child. I have been against this the entire time, and she finally broke. Shes decided to end it.

When she decided to end it 6 weeks ago, i felt relief, i wouldnt have to be nagged about a baby, i could get away from her spending money on clothes and other associated stuff. I moved fast to put the house on market and get financial contracts done. She tried to slow me down, but i wouldnt slow it down.

Now the house is on the market, ive been struck by intense grief. Ive begged her multiple times over the last 2 weeks to take me back (im not proud of this). Ive promised a baby, everything, but shes done.

I know i dont want another baby, it would financially cripple us with the mortgage. I also dont want to start again with a newborn when my youngest is almost 11.

Saying all that, im still completely grief stricken about losing her, i can barely function. Especially while we are under the same roof. I think i need to go and stay elsewhere until the house is sold, but i still dont know how im going to move on and be ok. Ive thought about ending my life, and i still might

If anyone has any advice or whatever, please help. I know ive been a dickhead.
