Advice

I'm having a second child that wasn't planned, by the time we found out it was to late in my own mind to make any other choices then to keep it. I have pcos so the signs aren't always there. The issue is my marriage. We weren't doing well to begin with and haven't been since my first born came. How do you women cope? I can't afford to be on my own with 2 kids and keep a secure life. I don't mind struggling but I won't put my children in a position where I can't financially support then 100% of the time. My husband is like speaking to a toddler so that has made things super difficult to discuss anything. When things are brought up I'm just whining and bitching. I cant win, I'm due in March and maternity leave isn't even half of what I make so leaving isn't an option. I guess I'm just curious how other women cope with these things.
