Parents forcing me to get married

So long story short I gave birth last year in November at 19 while still living with my parents me and my boyfriend who have been together for three years and think it’s about time we move in together especially for our daughter so she doesn’t have to go from house to house and soo we can have our own space as a little family but my parents have said that they’d be angry if I move out without getting married to my boyfriend and they wouldn’t support me even though I’ve told them multiple times I don’t want to get married yet.

What should I do ?
