confused

I posted a while ago a post asking if it was healthy feeling so lonely being married. . I've talked to my husband about it (and his smoking and drinking) he says he'll change but I dont see any change in him . I've been with him for almost 2 years married for 8 months. we have a beautiful baby girl .

he keeps drinking he keeps smoking and he hardly spends time with us . he gets home from work and gets busy working on a car or going out To a store and comes home 3 hours later. Idk what to do or think . im thinking of my daughter . I dont want her growing up thinking its okay to look for someone whose an alcoholic like her father... I dont know what to do . 😔
