There's so much I recognize in this, even without a +1 ;>)

Although I can talk with anyone, a friendship is completely different. I can even feel, here in Portugal, that some neighbors / villagers don't understand why I don't invite them over for a coffee, tea, lunch, dinner and prefer to keep ( the inside of ) my house a castle / secret. I much rather talk to them outdoor or in the local restaurant.

I have a couple of really good friends ( in The Netherlands ), but am closest with my family. I don't need loads of friends, even though I sometimes feel like being around more people, especially when I'm starting to be a little too much in my own head. Then, after spending some time around others, I soon long to be alone again and recharge my batteries. It's too much for me pretty quickly.

Funny enough, I still have to work on my self love ( treat myself even more as a friend ) but I think I'm slowly getting there.

I still hope your husband feels less lonely in the near future. I know - from experience - that it's easier said then done but it must be a huge help to have someone like you on his side :>)

Much love from a fellow Libra and mediator / introvert
