I want to divorce my husband because of his family

I love him and he’s a great guy but his family is too much they expect everything from him and he doesn’t know how to say no. I completely agree he should help his family if they need it but they have taken complete advantage of him and guilt trip him into whatever they want but they only do it to him when they have six other children because my husband is so weak and now they think they can do the same with me.

I am pregnant we are expecting our first baby and I’m already being told how to do this and that and how we need to find a bigger house so they can live with us I’m just at my end and my husband will not stand up for us. Anytime he says anything his mom freaks out and cries and throws a fit a literal fit saying things like no one cares about her or loves her and it’s emotionally draining for everyone around
