Where do I even start? (Help)

Ok so I f24 have been married to my husband m 25 for 7 years. We got married at 18 after dating for 4 weeks. (Stupid frontal lobe development yes I know now that was a stupid decision) And we have 2 kids m5 and m 9months. And I just don't feel the spark anymore and when I do my husband somehow always squashes it I can't be myself around him because he looks concerned. I am tired of feeling like property. I am tired of being treated like a child I want to do things also he thinks I am cheating on him with our friend. Like he threatened our friend. And I want out but I am financially dependent on him I don't know how to get out of this someone help. Edit he won't allow me to get a job or my license so someone help.
