Erase if wrong group

I just wanted to know if someone is on the same situation as I am and can tell me a bit how to proceed, I’m from méxico born and raised all my family is back there.

I’m one week postpartum and I can already tell my marriage will fall apart sooner than later or maybe I’m not Inlove with him anymore as I thought. He’s a great dad and I’m great mom we both are good human beings is just we are not meant to be together our chemistry is off and maybe I never wanted to see it until know. I want to make sure whoever is reading this understands he is a good partner and a great dad not a dirt bag but I want a divorce know he makes 3 times more than I do all his family is here and I know it won’t be an easy battle(legally ) because since I’m from méxico I’m planning to return there with my daughter if possible, again I will never do anything ilegal I want everything to be legal. what are the chances I can take my daughter to méxico with me and start our life’s there and maybe dad can come to visit once every 3 months and she can come during the summer ? I’m on a lost but I know 100 % I want to go back to Mexico.

She won’t be deprived of anything in Mexico my family in México does very well financially and can supports with no problem at all.

What lawyer I need to see ?? Thanks In advance
