So I want to know something about this .

So my ex who I dated 2almmost 3 years , we ended on good terms so we talk sometimes not often just around birthdays life events and holidays , and I've noticed something ..... when we was together he a guy who had resting bitch face (his words) I would tell him his just a teddy bear , and his still seems like the same guy but when I scroll on insta I see him posting alot about Bible verses and he never was like that till rencely mainly after he got married to someone esle (she's my age so to someone 20 years younger then him im not complaining just adding it as some info ) and I'm wondering if it's related to him being married to her and alot more since his having a baby boy, I'm not jealous or anything but it doesn't seem like him , he would post normal thing like x plane taking of from x place or something about one of the times with his kids like x and him having a good time at x place or having a lovely lunch at x place , or when the to younger ones was starting to drive . I'm wondering if he was normally like this always or if it due to his new wife that made him change to this god loving Bible verse posting person ? I'm not complaining I'm just noticing it alot and it's confusing me since he never seemed like this but he did have cancer last year and alot of other stuff with the oldest daughter (25 years old) going back to jail / prison (I don't remember) and I told him I hope she gets her shit together and do better for her self and lose the friends who dragged her in to the place she in now since they are the reason why she's in jail from what I seen and from what he said. I'm a little worried about the dramatic change that happened so fast , if you need more info comment and I'll do my best to give the info asked . Like I said I'm not jealous I'm just wondering and a little concerned and confused what could of done this , I don't really want to ask him since I think it be weird / rude to ask and if you think I should and that it really isn't lmk in comments. In advance thank you for helping me understand a bit more on this ik it's weird to ask this but the last post I saw from him made me a bit worried for him cuase or this I'm not sure if it's normal for someone to be posting alot about Bible verses I haven't had and God loving people as friends since I'm the black sheep and alot of people like that stay away from me since I have piercings , screached ears and some tattoos one being a cat with an upside down cross on my inner ankle (Noone sees it's a size of a quarter and my shoes cover it inless I'm showing someone my tattoos ) I have a large 1 for my dad and 3 small ones nothing bad other than the cat one all the ones that can be seen Noone notices due to them being on the inner arm an being small expect my large one that I got when I was 18 (I get asked if it's new and if I just got it 🤷‍♀️ so being on the inner arms Noone knows about them in less I'm reaching apparently)
