Separation: where do I start?

[incrediblecayote]

I have been married for over 10 years and we have 3 children. My husband flits from one addiction to the other; gambling, drugs, alcohol. As much as I love him, I really do, I'm just so unhappy.
Where do I start? If I ask him to leave I don't think I can deal with the upset and arguing, I'm just not strong enough. And what do I tell my children?
I feel like I'm begging for help, quietly from the corner hoping one day everything will be alright.

Start by contacting some of the support services/ charities that are out there, Turning point, Addiction U.K.who help support partners of addicts.
Relate offer counselling for couples and individuals too.
I suppose it depends on if you DP wants to improve himself, admit the issues and the situation or not and work together or if you tackle this on your own.
There is individual help and groups that put others in similar situations together to talk, heal and find support and friendship.
I hope you can find a pathway through.
