I 32M struggling with 40ms attachment to his ex boyfriend.

Hi I have been in a relationship with a male who is 40 for around a year and 2 months I am a 32 year old male. We got together around 4 months after his relationship of 9 years ended.

This issue i am having is he appears to be overly concerned/worried about his exes welfare and how his life is going. As far as I am aware his ex is in a new relationship and is travelling around the world enjoying himself. My partner has brought up on countless occasions how he is worried about his ex maybe going down a wrong path, worried about who he is surrounding himself with, worried about his exes relationship with his exes family etc etc.

At first I tried to console him about this and tell him not to worry about him but it has became a bit much. He told me yesterday that he had spoken to this ex and he let me see the messages and the message was him basically saying that he will always be there for him and if he needs comfort or reassurance then his ex can come to him for that. He then sent other messages to this ex saying "I hope you are okx" and then when he didn't get a reply he asked again "are you ok? Xx". When I said to him that I find that inappropriate and as his new partner that makes me feel uncomfortable as that is his ex boyfriend he just said to me that's what he is like as a person and he cares about everyone and anyone who has been in his life he will always be there for them.

Then when I asked him if he was over this relationship (in a very non confrontational way) he said there is nothing there and I have nothing to worry about and he loves me and wants to be with me...

There has been several occasions over the year where he has accidentally called me by his exes name in conversation and then been hugely apologetic afterwards and I have brushed it off/laughed.

There are also still a lot of pictures of him and this ex on his Facebook.

Am I wrong for thinking there is still a lot of feelings there? And am I justified in feeling confused and a little upset about this?

The conversations I have had with him regarding this just get met with that he cares about everyone deeply and he can't help it so basically don't be upset about it.

What would you do and how would you feel?
