Does anyone else’s baby daddy get worse?

So I’m currently on my 3rd pregnancy and my husband is getting worse. Before we found out I was pregnant he promised he was going to quit smoking weed and using nicotine pouches. Now I’m 13 weeks pregnant: he takes money from me to buy the pouches and when I don’t have any he takes from our oldest piggy bank (he has his own job so he has his own income). Obviously we are constantly fighting about it because he promised to be better but isn’t actually improving with the pouches. My first pregnancy we fought all the time too and with my second pregnancy it got so bad I had to call the police on him because he started breaking things. Am I just overreacting because I’m pregnant or is this a serious issue? It’s to the point where I don’t know if I can stay married because I just want one happy pregnancy and I won’t be getting that if I stay…
