Perspective....
Best to open a bottle of wine or do whatever the two of you used to do to connect and talk before you got pregnant.
Look at things differently. Having kids is a lifestyle choice. As humans we are the only animal that has that choice and it is a concious act whether by accident or not.
This is the life both of you chose. Having a family is an option. It is nothing to do with survival of the species, conformity, legacy, some on to look after you etc.
It is narcissism. Both narcissistic supply of love from having a child and the self gratification you get from we 'did this' this is our child and watching that child grow. You also get community approval.
There is a link on another thread to a good article on why people have kids and why highly creative and intelligent people have less.
When you look at that way - having kids is an 'alternative lifestyle'. The 'normal state' is before kids.
Because by having kids you are choosing to life differently - changes to your schedule, finances, responsibilities, lifestyle, diet, sleeping paterns, sex life - EVERYTHING!
Both of you need to understand that and make changes. He signed up to nightime feedings and diaper changing along with everything else.
Largely what we think and feel is a product of life experiences, conditioning and brain chemistry.
The child didn't just happen. You two made it happen. You did it and now all that comes with having that child needs to be dealt with.
Look at every problem as something to be solved not an obstacle.
Find out why sex is painful and do something to fix it. Fix your sex drive - you had it once and you can get it back.
Say - ok I am fine with the blinds but you need to find a way to keep the light out.
My husband didn't want me tiling the bathroom floor and wanted carpet because he didnt want cold floors. I now have tile with underfloor heating!
Depression is bio-chemical and it too has a solution.
Every problem has a solution and requires a concious decision. Try not to make curtains an emotional issue.
