Stressed since husband retired

I think I just need to let off steam. Long rant
My OH retired in December and I am really struggling with him being home all of the time. I have become so resentful and hate myself for it. He did work away a lot of the time so I developed my own routines. I find my lack of personal space a challenge. I spend more time upstairs as the tv is on constantly when he is home watching all kinds of junk.
I still have my hobbies and he does have his, but his are lone things that he does excercise etc. I have volunteer roles mixing with lots of people and enjoying a laugh. The friends we had have either died or moved to be closer to family and I am now lonely. I would like us to have more social interactions together as a couple. I am friends with people but we have no mutual friends as OH does struggle socially, all previous mutual friends have been made via things that I did and we did enjoy times with them. I am at a loss as to how to get him involved in making friendship groups as it would be nice to go out with others. Has anyone experienced this and how did you resolve it as any advice would be gratefully accepted.
