I feel so worthless .. 💔

I'm so jealous of all you ladies who have wonderful husbands! Mine is such an asshole too me! He has changed so much! He says I need too much attention but he doesn't give me any he is always on his phone! And we aren't living together I'm living with my parents because he smokes inside the house weed and cigs not healthy for a pregnant women and he doesn't buy any food! He spends all his paycheck on weed and video games and systems for his car! We never spend time together because he is at work but when he isn't working he just wants too be smoking! He never trys to call me or text me.. We go days without talking.. And yet when I do see him he says I always need too much attention.. He was the most sweetest guy when we first met and he showed me he loved me.. An then I married him and got pregnant and everything has changed.. I feel so depressed :'( he literally hasn't bought anything for our baby! All he cares about is weed! We don't ever go out on dates or even have sex anymore .. I feel like I'm just not good enough for him anymore .. He don't make an effort in trying to see me or talking too me..
