Am I wrong?

My girlfriend and I became parents around two years ago, our daughter is two years old (born feb 2017), almost three and we have had sex around 6 times since then (last time was on my s/o's birthday which was in March of the same year ) . I believe my partner is going through some serious,unaddressed mental changes since our baby that have caused her to become very irritable, suicidal, impulsive, depressed, and this is why we have yet to have sex again.

I want our sex life to get better, but until she gets better I just cant see myself being intimate with someone so broken... I feel wrong for depriving her of something but I feel I have no other choice until she gets better.

have you gone throuh this? did it get better?

any advice would be wonderful

I am honestly worried that this will end our relationship,
