Need some advice… 

Me and my boyfriend are currently in a long distance relationship (like 3-4 hours but used to be just round the corner). 

I am loving my life on placement as in my company there is lots of interns with me and I am getting to explore a new city. Unfortunately, his experience is not the same. He is by himself in the middle of quite a dull town. 

The only people he knows there is my mate and his girl best friend. I know nothing would happen between any of them but I do get quite jealous whenever they meet up as I like to see myself as his “special girl”. 

He’s recently opened up to me about how he is struggling quite alot with feeing lonely. I am really concerned for him as he isn’t speaking to many of his friends and getting out the house a lot. He comes to visit me lots and as much as I love it I also think it is important for us to live our separate lives. 

I know I should suggest that he sees his girl best friend more butI know I get major anxiety in these situations and it comes across bad to his :( My worry is that the more time he spends with her it’ll take away from how he feels about me. For example, going to her with his issues rather than coming to me?

Can someone advice me of what to do in this situation? 
- Should I suggest to him to see his friend more (and just try deal with the anxiety it gives me)? 
- How should I approach regarding balancing him and my friends (I think I worry if I don’t see him as much he will lose this attraction he has for me)

Sorry this was super long!!!
