Marital problems

My baby is 24 days old and his daddy work offshore so I've had him since birth. His dad even miss the birth and csm few days after we got out of the hospital. We having problems and idk how to deal with the hurt and painful words he said to me Saturday night. He Skype me and felt bad so he coming home so we can figure our marriage out. He wants to walk away and to me after three weeks after I give birth you want to leave me instead of working things out. I'm so nervous to see him after all those words he said through messages. I cried so hard my eyes was puffy til last night. My parents are not happy but he going to talk to them tonight to explain himself. He thinks its best if we part ways my son should be with him cause I'm not working right now. I just want to work it out for our son sake. I'm not raising him in two different households. We a family and I'll save my family no matter what for my son. Can I get some advice from any married couple I'm just in my 1st year. I heard the first year is the most difficult year of marriage.
