My fiancé has admitted to me he's jealous of our newborn and my son from another relationship how can I help him feel better?

My partner said he feels alone and it's like he's lost his best mate. Our son is 5 weeks old and he's a great father all round. However lately he's been quite sheltered and not himself. He's been drinking a lot more than usual about 7-12 cans most days and only feeds our son when I ask for help which to be honest I never ask him for help because he's always had a drink and don't trust him in case he has an accident.
I want to help my partner feel loved and not pushed aside but I don't know where to start. I'm always giving him a hug and the odd shoulder massage here and there and a kiss. Do I need to tell him I love him more or something why is he so sensitive all of a sudden I'm the one with baby blues o_O how can I help him?

Bloody hell woman, how haven’t you kicked him out yet?
Whining is extremely unattractive and I’m amazed you have the energy to give shoulder massages as well as look after a load of kids ( I include him in that)
He sounds like a nightmare, you don’t need to help him do anything

Thank you for all your opinions. I've spoke to him and he's been waiting to see someone since I've been pregnant takes up to two month or so on the waiting list. I just don't know what to do. I've had depression in the past and I got left because of it. I don't want to do the same to him because when he's in a good place he's a very good man. Just not when i need him to be. I'm still living on my own with my sons and he stays over we've go a house viewing this week and my head is telling me not to move in together but my heart is saying go for it :/

I bet he's a really shit dad to his other kids isn't he? I bet you look after them not just when he's working too. Let me guess, you feed them and do all the grunt work. And you're giving him shoulder rubs when you've just had a baby.

He really saw you coming :(

Hahaha trust me I kicked him out and to be honest I can't cope with it all it's too much for me to handle I've started taking vitamins and St. John's wort tablets for low mood. My head is crumbling even more everyday if I'm honest

Do these men really exist jealous of a newborn no wonder his ex isn’t with him. I would leave.

Kick him into touch and that's more than half your workload gone. You'll be amazed how much better you feel.
