I don't know what to do

[Dani80]

I have been with my partner for a year and half. Everything was great until a few months ago.
He's always enjoyed a few cans after work but the last few months he's been getting up earlier so he can have a couple of Stella's before work, on his days off he gets up and goes straight to the fridge for a can and will drink all day apart from when hes having a nap but starts again soon as he wakes up.

He is starting to pick at everything and anything lately, complaining constantly about things me and my kids do. Yesterday my older boys treated me to lunch at pizza hut, soon as I'd picked him up from work he started, "no point having tea now you've had pizza hut" "you must have been there 2 hours because you was only driving home when I phoned" he just kept making digs and saying hes not eating now no point but I personal think he didn't want to eat so he could get more drink in.
He slept downstairs las

He's neither use nor ornament

Perfectly put.

I think you have confused love here with codependency. You’ve been useful to him till now and he was on his best behaviour until he was not. Tell your children what he is really like, they likely know more than you credit them with.

examine why this man was allowed into your life at all?. Look at your boundaries here and raise your bar going forward. You were targeted by this individual and deliberately so, he saw in you a soft touch and someone he could use and otherwise exploit.

It is, but it's a really old, familiar, well-known phrase - I think it must be a quote from somewhere or other.

But yes - he's neither use nor ornament, OP. Get rid!

he moved in with me and doesn't pay much to the rent as he's never got any money from the daily alcohol and betting.

What on earth is the attraction to a man like this?

You are setting a dreadful example to your kids about relationships. Sorry.

Why let him live with you. I say to all boyfriends,, 'no moving in until we've been together at least 5 years'
I've never fallen prey to a cocklodger.
