Feeling abandoned

In what way? Motherhood can feel rather isolating. It does feel like you're standing alone on an island and your partner is far away. Communication Is key. You are both going through so much and coping is not universal. We each cope differently. Your perspective might be different from him. Ask yourself these, does he help with the kid? Does he give me some breathing room when I need to take 5? Does he share the night burdens? Am I a single mother in a relationship? Ask yourself the basic of what you need and start the conversation from there. Sometimes we communicate that we have a need that has to be met and all the other person hears is give me more. He says he feels unappreciated, you can start from there. "Love, thank you for your help around the house, Love thank you for taking the time to bond with me and the baby as a family, Love thank you for giving me a moment to nap". From there you can segue into the "Love the baby is asleep, would you like to cuddle, I need to recharge with you" and so on.
