Confused ...

So I’ve been with my children’s father for about six years we have two girls four and two year old

He’s had a past of drugs and alcohol I don’t know at what extend hes still on that he won’t take a drug test… When I met him he was broke but would act like he had money he started a real estate business when we were together and it took off and since then he broke the engagement I had just had my second baby and was devastated we were looking for a new house he said he was going to put both our names on the deed yet he went to the closing by himself and kept lying to me that he would change that later on bottom line that never happened and now he’s doing everything to Break us up…

On Christmas morning out of the blue he woke up to get the girls in the morning he never does that he says that’s my job since he’s working from home… And he didn’t wake me up and he took the girls downstairs to see the gifts I texted him to confront him and he flipped out over text and said he wasn’t going to participate so he basically locked himself in his room the whole day we were supposed to have people over he said if they came he would call the cops… The girls kept crying knocking on his door and he was telling them that his tummy hurt… So today is New Year’s and my family is in Europe so we have this tradition that we celebrate New Year’s with the girls at 6 PM so they could be up and ring it with my family on FaceTime... well he reluctantly showed up at 5:45 he had apparently gone for a walk in the middle of the night while raining… He was completely miserable sitting at the table and couldn’t wait for the girls to go to bed I asked him if he wanted to watch TV together he said no I wanna be by myself leave me alone I said well it’s New Year’s he goes I’m too tired I’m just gonna go to bed… I’m sitting here alone with the TV on mute thinking water in all the hell is going on!!!??? Could he be on drugs again the change in his mood is so weird he also snapped at the girls right before bed:((
