Either I have trust issues or something's up..

So yeah, he's been leaving every morning at 3am saying he had to work that early, then just today, I tried to wake him up because it was almost 4am but he said he's gonna get some more sleep and left to work at 7? I cant help but feel like he's hiding something, he has me blocked on Facebook, we had sex once! And then I tried to have sex with him many times but he was too tired or was busy with our baby he says, when clearly the baby only wants me, he didn't even kiss me and hug me like usual when he gets off work which is at 6-8pm. I'm sorry I sound so insecure and untrustworthy but he even sends me screenshots of posts on facebook, but when he's home, he doesn't have his phone, it's always on silent in the kitchen on top the closet/pantry with his work stuff.. he doesn't use it at all around me.. is it time for me to ask questions or should I just leave it alone? :(
