I see some red flags here.........that when you cry he isn't concerned just calls it 'weakness...!' That if you are honest about issues it leads to a fight, that you feel you have to walk around on eggshells...Sex is a huge part of marriage, not a small part, to me or to you from what I read about your sex drive..also I have read about men who change after their wife has a baby, and this may be the case....what does he say about marriage counseling? What if this marriage doesn't work, are you prepared or have some sort of a plan B? Write again......
