In desperate need of advice🥺

Hello, so a little background on my life I am a recently married 21 year old first time mom with an almost two month old son. My husband and I were long distance and when I got pregnant he ended up dropping everything and moving from Atlanta to Las Vegas for me. He left his family and his job which paid very good and has not been able to find anything like that here. Recently, my husband and I have been having a lot of relationship problems due to our financial situation. He is used to having money and says he does not feel like a man anymore. We have been arguing nonstop (we love then hate one another) and I feel that if this keeps going on we will end up getting a divorce as arguments keep getting bigger. A few weeks ago we agreed on moving to Atlanta in January so he can get his job back and hopefully it will help smooth things out with us as we will now be able to live comfortably. My dad has started having health problems this year and we just found out he will need a liver transplant or he will not live too much longer as his organs are starting to slowly shut down. The doctor has not given a time frame so it could be up to a few years or less. My decision was not easy for me but now this has made me even more reluctant. Idk what to do, we are struggling here and have a better chance in atlanta but I don't want to leave my dad now..This is hard for me because we have a baby that we need to support and we are barely getting by here but my dad and mom love the baby and I and I don't want to abandon him. PLEASE HELP.. On one hand, we can give our baby everything he needs and within a few years will even have the means to be able to buy a house there but on the otherhand, my dads body is slowly shutting down and I don't know how much longer he has but If we stay here, after paying just our bills we will barely even have $20 left for gas.
