My marrige is starting to become unstable

With all the stress of bedrest and the unknown of how this pregnancy is going to end is taking a tole on our marriage.  Bedrest means Martin is basically on bedrest as well and just going out to mow the lawn with an infant in the house is a major issue.

I didn't want Martin's mom near me because she stressed me out even more.  We will just say that during our first loss and during my pregnancy with our first son she wasn't exactly supportive.  

It's hard being couped up in the house and for those who came to help after a while they felt the same.  

We moved into our new house and Martin would take our son for walks.  All the neighbors thought I was anti-social because I never came out to meet them.  Why didn't Martin tell them his wife was on bedrest with twins is beyond me??
