Big “D” word 🥺

I’ve been married for 2 years, with him for almost 8. I’m 39, no children of my own. He knew and agreed to children prior to marriage. I did conceive a yr ago, but had a mc. He wasn’t excited about the news of me being pregnant. In fact I was surprised it happened. I want children, a least one of my own. He has a 15 yr old and supports his ex’s 23 yr old son, not his biological. He said it before but I didn’t think it was a big deal, but he’s telling me “No! We don’t have the money for a kid rn!” What?! We don’t even have sex!! In the last year maybe 12-14 times, in 1 year! Once a month! Between that, his excuses of denying me a child and making it seem like “I should be ok with it” I’m mad! It’s always been a problem that we don’t do a thing together. He twists everything I say around, he never wants anyone to come over (to the house I bought before we got married, the house I fully renovated) I feel trapped! I really want a divorce. I tell woman in abusive relationships to leave ALL of the time being a domestic violence advocate, but I can’t figure out how to do it myself! He lives in a house I need to sell. I know I’m going to get sucked back into the cycle but I don’t want to. Before I jump into it, what should I do first?? I’m so lost and overwhelmed.
