What kind of visitation scedule will they give him

We cant agree to anything. He wants alot of time and i just find it unbelievable that iv always done everything on my own when we were together & he acts like he deserves 50/50 😞 he left me dec 2 and since this day hes refused to see the kids because he wanted to take them as long as he wanted or in his terms. He would refused to work but guess who has a job now. I guess he seen shit got serious after begging him and encourage him to work nothing would work. I feel so devasted to give my kids away and feel so alone esp when it just been me and them the past 2 months. I work a early shift so i can have the whole day to be with them. I didnt want this to happen and did my best to keep my family together. He gave me a hard time to talk to him until today it was my sons 1st birthday and he texted me saying happy birthday to him. I asked if he wanted to see him to give him a hug and he said he couldn't cus he just started a job and had to work. (Last week he threaten to take me to court) i think his mom spoke to him because i told her what he told me and he said he'll find out what his scedule is going to be so he can take the kids. Which was what i FIRST told me and he flipped off on me that last time. Idk what to do. I already spoke to lawyers but idk if he will be willing to settle something between me and him so we don't take this to court. I dont want my kids to sleep overnight, one lawyer even told me they were still little for overnights. My daughter is 2 and my son just turned one. My kids father always deals with getting high everday and abuses the shit out of it. I told him a month ago i didnt want him being high around them or them coming back smelling like weed because he use to smoke in the house and he flipped out saying it was not my business no more. Im still going to mention this when he tells me his scedule but for right now what do u guys think of my situation..how many days/ or a set schedule would be reasonable? One lawyer told me to keep it minium since i am the main provider (I forgot the word she used) and explain to him later intime we can add more time. Not sure how he will take this
