I feel torn down I need your help girls

So hubby and I have 3 beautiful kids.Last night we went to a friend's BBQ and had a good time went home everthinv felt great not even 30min after we get home i feel him distancing himself and start being a bit short with me. My inuition kicks in and I ask if everything is ok..he says yes i let it go.today I wake up get my youngest ready and got to work i go in at 730am. Go home for lunch and im basically given the silent treatment as if i didn't even exist.i ask whats wrong i get ignored. I have been walking on eggshells around my hubby due to his trust issues. And try to make him feel as reassured as possible. And today its as if we took 100 steps back...idk what else to think but to be angry....I've done so much and still I feel lonely...should I just leave him alone and give him space ..but I've done nothing wrong...
