I have been with DP for nearly 5 years now, we are both in our mid 20s. We get on great, and have always been in a very supportive relationship. When we first met, we were both very social with our own friend groups, fit/sporty, enjoyed foreign holidays and spontaneous trips.
A really toxic workplace lead to him taking some time off and being prescribed medication. During this period he also stopped all sport, and didn't see his friends much at all. His family and I did all we could to support during this time, which seemed to help. He found a new position which he is happy in, but with COVID starting shortly after, this meant his social life continued to suffer (as did everyone's really).
After things started to get a little bit more normal, I found I was also not having a great social life (friends in different cities now after uni etc). I used local meetup groups where I met a couple of great people, and joined a new hobby group which has been amazing socially.
I would love for him to go out and make some new friends, find a new hobby, or even just make some plans to travel as a couple etc. I've offered to help with this, or he could come along to my fitness hobby as they are a social bunch and have a good guys group. However he is too anxious to do any of this, so if we do things with friends, it is with mine and their partners. If he goes out, it's with me or his family. I just feel a bit drained - every time I go out I know he will be sat alone at home on the sofa/in bed. I don't resent him as such but I am starting to pity him almost, which removes a lot of the sexual attraction that was once there. He still feels the attraction to me but I'm really starting to lose it.
I suppose I am just looking for some advice, anyone who has been in the same situation? Would I be unreasonable to give some kind of ultimatum?
