Advice would help !

Cause my panic attacks are hitting me very hard today & I hate it . Cause I’m already pregnant ! So me & my sons dad been together 2 years off & on & we are now on baby #2 together but I have 3 ! We been together for 3 months straight & everything was good at first , made love , went out , I drive his truck & drop him off at work etc , it was great gave me no reason to think otherwise ! Anyways for the past week since I found out I was pregnant last week (PLANNED PREG) , he has been more distant we literally haven’t had sex in 6 days , he doesn’t cuddle with me anymore , he don’t tell me good morning like he has at the beginning the small little things that make me feel good about our relationship , lately he has been blowing me off in everything I say ! I’m pregnant so right now is not the time to treat me like cause I’m an emotional wreck I’m crying as I’m typing this cause now I feel worthless & hopless , I’m only 5 weeks & im thinking it isn’t gonna work out with us & ive done all I could do to make this work , I cooked breakfast like he wanted , tried to wake him up for it he said he would eat ‘ he was suppose to go to work I woke him up to get ready , he didn’t get up went in an hour later , & didn’t even acknowledge me or the kids hopped straight on his phone & contacted his employees cause he a store manager ! When he end up getting up he didn’t even eat so now the foods obviously cold & nasty now , like I’m at the point I wanted my next relationship to be with someone I planned in marrying & wanted kids and here I am about to be a single mom of 4 kids & im on edge . But I need hope cause right now I’m hopeless & I don’t think he cares how I feel or cares at all that I’m carrying his child again .
