How to feel closer to my hubby

What can I feel closer to my husband been with him 6 years and ever since I got pregnant in 2016 he’s been very distant. We have a 14 month old together and we don’t hold each other anymore or anything like that. He’s just on his phone playing slot machine casino games when we go out.... I thought he was cheating so I had a talk with him and asked him if he was seeing someone else. He responds with “no”. He then goes on telling me with a face of guilt that he’s addicted to drugs.. I’m not surprised.. This whole time that’s the reason for him no hugging me etc.. now we are trying to get him help. And no I’m not leaving him as that won’t solve anything.

Anyways What can I do to get closer to my husband.. I want my best friend back.
