I need guidance

So me and my long term partner are for sure alcoholics. Him more so than me. He's been drinking liquor for the past couple of years. Finally he switched to beer about 6 months ago. He's finally down to only about 3 beers a day. Hes been having what I would consider severe symptoms of something serious and I need to know I need to force him to go to the ER or if this is usual of detoxing from alcoholism. The symptoms are, weight loss, he bruises very easily and very severely, his blood is very thin (any open wound bleeds soo much), , he is very sore and very weak. His skin is very agitated, like tiny little spots all over his back. Please just tell me if these are normal symptoms or if he needs to go to a doctor.
