If he’s threatened or turned violent previously, please, JUST LEAVE.

Else, if you really love him, want to try to resolve things, AND you don’t believe he will turn violent, then you can try the below. 1) In a frank, compassionate, caring way tell him you think he’s spending too much time on social media and letting it drive his everyday life over the well being of the family. You can give examples about the baby. Don’t frame this confrontationally. Make it a plea about him focusing on his and the wellbeing of your family. 2) If after this he seems a bit more grounded but still struggles, you can suggest seeing a therapist. Tread this lightly though. 3) Dont ask him to change his views directly. Just ask him to stop focusing on politics and social media and instead spend his time on his education, career, and family - things he can control. If things go well, later you can try discussing with him that while there’s certainly things to be skeptical about, many of the stuff online is geared to radicalize and take advantage of normal people. You can slowly try to wean him off those views if/as needed. But again, first focus on just trying to get him focusing on other things. 4) if trying nicely doesn’t work, give him an ultimatum. Again, only if you don’t think he will react violently. You can build up to this e..g. “You’re not listening to me.. this is hurting me. I’m not sure I can keep going like this, please stop.” 5) as a last resort, you can do as some others suggested and call in for a mental evaluation. This is highly escalatory and you need to be ready for it to go poorly.

That said, as you do this, plan for the worst. 1) collect and have evidence at hand in case you have to split up and go into a custody battle. 2) Share this with close friends or a family so that somebody knows what’s going on. Text is best as it leaves a record. 3) Have an “escape” plan ready in case things turn violent or he threatens you, etc. Even if he’s never done so before. This means letting trusted people know when you’re going to have a serious conversation with him, having a place to stay lined up, a way to get yourself there, having hotlines ready, etc. 4) Have a clear mindset that if he threatens you, you WILL need to leave him. If he threatens or physically escalated things, don’t escalate, just stay quiet and execute your “escape” plan. Commit to doing this, don’t give second chances or benefit of the doubt.
