DP has friendships from way back, which are important to him and which he devotes quite a lot of energy into maintaining. This, I think, is a good thing?
His best friend is clearly feeling neglected since we got together. Best friend is a married man with DC and a busy job. DP had been single for a long time before we met, so their normal had been that DP was available when friend could fit him in. Everyone was happy with that.
I am firmly of the view that this friend is, and should continue to be important to DP, but they speak (as in actual conversations, not text) around 3 times a day. And that's when I'm with DP, it could be more when I'm not. When we're together, even when out with other friends, DP cannot let these calls drop. He will take the calls regardless of where we are or what we're doing, like they're the most important thing in the world. E.g at dinner with friends.
We all have a shared hobby that we sometimes do locally or sometimes travel for. There are venues all over the country. Friend is very rigid about which ones he wants to do, often travelling long distances. He complains DP doesn't go with him anymore , but won't be flexible to go to ones either nearer to home so DP isn't away all day, or to come to ones we are going to with other friends. I'm more than happy for DP to go alone and be out all day, all day, but DP prefers to get it done early and be back to have some of the day to do other things (with or without me).
Sometimes it feels like friend is a jealous "wife" who then finds fault with everything DP tries to do to solve things.
DP says he's used to being at this man's beck and call because their different circumstances meant that for years he was the one with more time and it's a hard habit to break, but something feels off.
Or is it genuinely just everyone (including me) getting used to each other and the change.
Fwiw I like the man and we've got along fine on the odd occasion he has joined us.
