As Kerala said, this needs nipping in the bud before you give up on having a life.
It might be a few months till you feel ready to leave DS with anyone but when ready and don't leave it too long, register with Sitters, we used them too, the sitters themselves all had relevant childcare experience e.g. child-minders, nursery staff.
As soon you feel ready and don't leave it too long, take up a regular hobby, so there is one night a week that you go to your dance class, your yoga, your bell ringing, your stitch 'n' bitch, your curry night with friends, it doesn't matter what but it reinforces for you and your DH that you are a real person with a life outside the home and he is perfectly capable of running the bedtime routine.
You may find yourself saying "Thursday is choir at 7pm, Thursday has been choir at 7pm for the last two years" but you will be walking out the house child free and getting some headspace back.
I can't tell you the relief and delight at sitting chatting to a new found friend and thinking "I don't have to rush home! DH is there and he's taking care of everything, I can just be me for a bit longer".
