YAB 'a bit' U, but I can understand where you're coming from.
I have had some good, valuable friendships over the years, and some awful ones. A few have lost touch with me, (ghosted me,) and I have lost touch with a few too - (ghosted them.) Some friendships just burn out, and some can be hard to shake off, some can be invaluable, and some can be a pain.
I am having some issues at the moment with a woman who I met 3 years ago or thereabouts, who lives 10 minutes walk from me, and gets on my tits most of the time. I thought she was OK to begin with, but soon discovered she is not a nice person. She tries to make out she is, by saying to people 'oooh let me know if there's anything I can do,' and offering to do duties in the Church, but bails almost every time on anything she promises.
In addition, she makes catty comments about people, and has made snide comments to me and my DH (and her partner has made rude comments too, a number of times,) and they both only bother with us when they want something. But this past couple of months, I have started to avoid her, (rushing off with 'I'm terribly busy, I need to be somewhere' type comments, and not returning her texts a few times,) and she has gone into meltdown! She has got THREE different people to contact me (phone, text, AND a fucking visit,) in the past 2 weeks, to 'see if I'm OK!' I am of course, and am very chatty and bubbly, when speaking to anyone else, and the people report back to her that I am! 
A month to 6 weeks could go by without a flicker from her; no text, no call, no contact, nothing, not even replying to MY texts, always turning up half an hour late for meetings at the pub, on the occasions we arranged to meet, (and her partner not being arsed to come at all sometimes.) But now I am/we are behaving the same with them, she is having a meltdown.
I have actually said to myself recently, that if we move house, I am never making friends again, but I have several other friends where I live, (who I see once or twice a month or so for a coffee,) who are quite pleasant; good company, intelligent, and interesting to talk to; so I refuse to let this one woman ruin my life.
I do agree with much of this post by Odin'slovechild; (below in italics...) not all, but most. I don't want people in my life who expect constant favours and lifts and who want to borrow stuff/money etc. I have had too much experience of people using me over the years, and now, although I like to have a few friends, I no longer want very close ones. Just ones I see maybe twice monthly for a coffee. I have enough responsibilities in my life (family/part-time job/kids etc,) without some so-called friend badgering me for a lift to hospital, or to the other side of the country, or to lend them £100 or something. Similarly though, I will never expect anything from any friend. So I think I am being reasonable.
Here is Odin's post...
Friends are overrated.
However encouraging people to not have friends isn't the answer. Teaching people to be completely independent and not rely on anyone else to help them out is a valuable lesson lots of people really need to learn. I don't have friends. I hate the expectation that I will help them out or do favours for them. I also hate that 'friends' expect me to hold the same opinions and values as them. I want to do what I want the way I want and without judgement or confirmation from 'friends'.
I know a lot of people who cant seem to cope in life without the opinion of another person. That's a dreadful situation to be in.
