I think my husband is depressed

Da

I went away for the week with the kids leaving my husband at home as he had to work and when we got back it was a complete 180 he keeps snapping at me and the kids all the time my poor little girl dosent know what she does wrong half the time when he yells at her she is so confused and dosent know whether she's coming or going he screamed at our son today because he accidentally punched him when he was trying to stand up I rush to pick up my son because he was petrafied and screaming looking at his daddy my poor babies dont understand why daddy dosent want anything to do with them as he is was such a loving caring father before we went away and now he is a different man and my kids are scared of him and I dont want them to be scared of there daddy I made an appointment today for him to go and see a shrink tomorrow and maybe they will help him sort it out I am worried sick that he will hurt my kids right now I am sleeping in the same room as them and I dont leave them alone with him I know hes there father but I dont trust him enough to not snap and hurt one of them I love my husband with all of my heart but if I have to leave him for my kids safty then I will no matter what and plz if you ladies can I need some advice as I am not coping very well with this at the moment and it's hard because we are expecting baby number 3 and he has known about the baby since I found out because we were togther when I did the test

These were all taken before we went away he doted on our kids and now he treats them like there just big annoyances to him
