<human>: I've been in a long distance relationship with my partner for over 3 years (I'm 20, F/Q).  We see each other 2 weekends a month, and I sometimes stay with him during holidays. We're both agreed that we're a strong enough relationship that we're likely to be together the rest of our lives. We're pragmatic enough to know that it might not work out, but we expect it to.

I'm at university in a city I love and he really likes. With my parents help I have a mortgage on a nice house here. He's at a job he hates in a city I hate and he only likes a little bit.  He's openly said that the reason he doesn't want to move here to be with me is that he's scared of losing his social support networks-friends he's hung out with for years. This is of course an entirely valid concern-needing to make new friends in a new place is an intimidating thing. He also suffers from social anxiety, which obviously makes it more difficult.

I'm planning on taking him to special interest social groups (gamer groups, anime groups, metal fan groups, etc) to try and help him meet people he can form new friendships with (then leaving the groups myself because its important for him to have friends and spaces he can go to without me-I'd just be going initially because he'd be too shy to go to something alone until he'd already met people there), but I'm not sure how effective this will be.

I'm looking for any advice as to how to make this easier and more effective. How else can I help him to build a social network here? How can I make what I'm already planning to do work better? How can I do any of this when he's only here 2 weekends a month?

Can you give me the gist of the text in a nutshell?
<bot>: My boyfriend is scared to move in with me because it would mean leaving his friends behind in another city. How do I help him make new friends before he moves here?
