Help me 😢

Background info: I’ve been with my partner 5 years in June, we have a recent 1 year old and have been engaged a year also.

Pretty much following our baby being born, he developed a gambling problem for approx 6 months so everyday lied to my face about where he was and reasons he couldn’t get home. I know it was a problem so I tried not to judge him and he’ll him recover. Since then we pretty much struggled with money trying to recover from his binging gambling. He also has admitted to a binging drink problem. So when he starts and at the pub with his mates he fjnds it hard to stop. 2 nights in 2 weeks he didn’t come home and stayed at his mates where we were arguing about him not coming home on time. He’s saying it’s depression since August but hasn’t been actively speaking to someone or family or a doctor after going on tablets for only a month.

I want to keep my family together but don’t know what to do. He hasn’t been living at home for almost 2 weeks as I said I needed space to get my head together. I feel like I don’t trust him and don’t know what I’m meant to do?

I recently started talking to a school friend (male) he’s always been super flirty, just his personality, and now I’m worried I’m starting to resent my partner even more and want to talk to this friend more.

What am I meant to do?

Should I leave my partner?
