In desperate need of advice

Em

So I have a son who is 17mo with a guy, who I do not get along with for other reasons that don’t relate to this post....basically, if he can’t have me....I’m am every name in the book....and talks down on me to EVERY person he possibly can...I am now married to a WONDERFUL man, but unfortunately his next two years will spent finishing up his contract with the army in Germany. I am currently in a custody battle with my sons father, he will not reason what so ever and is looking at 50/50 shared parenting. My lawyer offered him 3mo/3mo, so I would have him for 3mo, then his father would have him for 3mo....he denied, stating he would do 10mo/2mo.....which is ABSOLUTELY unreasonable if you ask me...he refuses to sign the passport for my son to even go to Germany to visit, let alone stay over there with me while I have him for the extended period of time....so my plan on being with my husband as much as possible is down the drain...on Saturday...I found out that I am 4 weeks pregnant....I truly do not want my husband to miss out of the first year and half of his FIRST child’s life, I think it is unfair and he will be absolutely miserable. He’s already crushed that he’s missing out on being around for my pregnancy....does anybody think that I should move to Germany once I have the baby? He will have paternity leave for 6wks after the baby is born, and I considered flying the baby and I back with him so he didn’t have to miss out on that experience...but on the other hand, what do I do about my son? My heart is absolutely torn and I am clueless about what to do right now...does anybody have any advice? Or even experience in a situation like this?
