How to know if my husband still loves me?

I have been married for almost 3 and half years, and for about a year my husband changed.. he started to not care about me at all, if i’m sick he would not do anything at all, stopped helping me with house cleaning and raising our kid. Also he would not come home unless he wants to sleep, like once he wakes up he take a shower and leave and comes back at around 2-3am, he started to shout at me more for no reason at all, gets angry for nothing, if im doing something he would talk bad about it saying i can't do anything right.
I did everything to help with this situation, i dress nice.. look nice.. smell nice.. always positive and have a good vibe but he stopped looking at me, last time he hugged me was about 6 months ago (thats when i stopped hugging first) let alone not kissing me.
Now im just miserable that he's not helping me with our son and letting me do everything for him, just today i asked him to take my son so i can go out with friends and he rejected… he never took our son alone…

Is there any way i can get him to act right?
