Anyone going through this or went through it

Are their any newly single mom's in here my husband told me last night he thought being married was what he wanted but has come to realize it's not. And I'm done fighting for him to stay so I'm just gonna let him go I can't force someone to be happy that's just not ever gonna be happy... .and i was just wanting some support and what do I do from here. We have a 2 year old little boy who adores his daddy so much how do you explain to them what's going on? Or do u just leave it alone until they ask questions. Also 28 weeks pregnant with our daughter so have to try to remain calm and not stress as I'm already high risk and have pre eclampsia so definitely want to stay calm.
