Need a man’s opinion …

Husband changed his number 2 weeks ago and refuses to give it to me…he’s been texting me thru an app…I only found out he changed it because I tried calling the old number restricted…he refuses to give it to me says he doesn’t meant me “hacking his phone” because technically I could get like app codes sent if I have his number?? Also he refuses to add me on his social medias, says that I embarrass him with my posting, his shit doesn’t say he’s married…idk the whole thing is super sketchy…please tell me your take on this, I mean it’s kind of obvious but I need to vent and get feedback
