What you've posted there, could actually word for word be written by me. I know for a fact (even on Tattle lol) I stick out like a sore thumb and don't fit in
For me, I spent a few years at home with ill health, caring for a dying person and my range of other people became a very small circle. At one point, I found myself sobbing to the Postie

simply because they were the only human to ask "how are you today?". It's so easy to become shut down and out of touch of how to converse with others.
I'd tell family the same thing at least 5 times, because it was all I had to offer on the chat front
So for you, it may well be that you are not boring, or can't communicate, it may be that you are stuck in rut and it's left you feeling a little flat (and with Covid - who isn't feeling like that right now?). Although you may feel others have a lot going on, this is a lot for you, so you have every right to speak out about your feelings.
With your OH, there's a few things, I know at the moment, people are working longer hours to catch up on things that have grown over lockdown, so if your OH has a long day, maybe chatting on a phone all day, then they won't really want to chat away, they are just tired. For those occasions, sometimes it's good to just let them go to the loo, chill a bit, then ask them to let you know when they are free for a natter and catch up. Being pounced on as soon as you get in, never sets up a good platform to engage with each other. One of you resents it as you are tired and drained, the other resents it because nobody listens.
If you both have weekends to share, then see if you can organise some couple/family things to do (if you have children, see if you can both have a few date night type things), we can lose some of our ability to chat and have fun, because life is a treadmill and boring (not us) x
