I'm so fed up trying to make friends and maintain friendships when it feels like such a one way street so much of the time. I'm as sure as I can be that there's nothing seriously wrong with me - I'm a bit quiet and reserved at times but I'm kind, polite, occasionally funny, I don't mistreat people as a rule and, as far as I know, I don't smell hideously. But I don't seem to be able to hold onto friends - I find it hard to make them but seem to manage often enough and things go well while it's easy for them.
I've had seemingly fantastic friends while we've worked together or lived near each other or had something else very obvious in common - and I don't just mean polite acquaintances, I mean go out for lunch, spend evenings out, phone each other etc. But then if it becomes any harder for them or I become less 'useful' - ie, they move away, change jobs etc - they just seem to drift off, rarely contact me again and seem like it was all a bit of a sham. I know this happens a lot but it seems to happen to every single friendship I make - I'm struggling to think how's it's me putting them ALL off but other people manage to hold onto at least a couple of friends - I feel like I'm permanently hovering around 0.
Most recently it's hit me harder as I've realised my 'best friend' (who's often called herself that - it's not me being clingy!) is quietly ditching me as we've moved a couple of hours away so I can't just pop round or nip out for coffee anymore (although I've already visited her 3 times and she's said nothing about even trying to come and see me).
The move was planned for ages and talked over with her loads and she never had any problem with it so it's not like I've done a moonlight flit and pissed her off. Yet now she never phones me, I've stopped phoning her now as it's just embarrassing to be told she's in the middle of something and will phone me back but doesn't. She only texts or Facebooks me in reply to a message from me, and then seems more and more distant and not particularly bothered. Yet I'm good enough to be used in tags on FB to make it look like she's got loads of close friends.
I'm realising more and more that, especially since she's had a child, she's far more concerned about appearing popular than actually having friendships - I've seen her go OTT to befriend other people only to virtually ignore them after the initial 'honeymoon' period. I didn't think she was like that 
It would be sad but understandable if it was just a realization that she didn't like me that much but was too nice to say, but I'm her ds's godmother (she asked me to be, didn't volunteer myself), she regularly calls me her best friend, we've been friends for over 8 years! It looks objectively like she was just using me for a friend while it suited her but even if I think that of her it can't apply to everyone. Should I just give up on having friends at all and become a recluse? (besides DH and DD!)
