Hi,
I'm in a relationship with a 5 month sober boyfriend.
The beginning is very hard & it is important to take a step back from the relationship rather than try to move things forward.
It is very important that he put his sobriety first & focus on that.
It is also very important that you focus on yourself so that you can be fit, happy & healthy.
My advice, just be there for him for support in the early days. If he needs to talk let him talk, if he needs a hug give him a hug but don't try to push the relationship.
My boyfriend felt numb in the beginning too & was depressed,anxious & a whole heap of other things. He now feels great & is getting better day by day.
If you are patient & it is meant to be then the relationship can develop over time. There is no rush is there?
Just work & focus one day at a time.
Hope this helps.
