To think my friend is ungenerous in only buying herself a concert ticket?

Not sure why she isn’t getting you a ticket, she’s having a free mini break!

I would find it very strange and insulting, especially as the tickets aren’t expensive and she stays so long!

I would nearly be tempted to say unfortunately you aren’t going to be around the weekend of the concert …..then maybe the Penny will drop because otherwise it might become a yearly thing

You say she’s a little socially awkward. If you like her then why not accept that this is her foible. For the price of 50 quid (ticket price) I wouldn’t get into a situation of trying to correct your friend’s behaviour with an uncomfortable maybe unpleasant conversation. If on balance you decide she is one of life’s ‘takers’ then distance yourself.

If she stays with you 5-7 days she's bu not to buy you a ticket, it's very mean.
Next time tell her to get a hotel.

I think that if she wants to stay with you she should at the very least invite you to the concert. If she is staying for 5-7 days she should be contributing to the expense of you having a houseguest. Do you invite yourself to hers to stay? I think I would say to her that she can’t stay as the dates aren’t good for you with other commitments

With the amount she's saving by staying with you she should definitely have got you a ticket and paid for it!

You don't need 'inviting' to a gig, its a public thing you can go to if you fancy it not a wedding or private birthday party. She is literally telling you about it and that she is going so just go. She probably thinks its a bit weird your not going given its your shared interest, probably never crossed her mind you are sitting at home waiting to be formally invited to a concert.

Why should she buy you a ticket, they are really expensive now even for small bands.

ODFOD!

OP has said that she pays for meals out when she at her friend's but the friend doesn't return that favour and when friend stays at her house, she often goes out with other friends without OP, thats rude, she is treating OPs house like a hotel! OP hasn't said she does that when she stays at her friends house.

I wouldn't expect her to buy my ticket, but I would kind of expect to be invited, especially if it's something that you've always done together. And I would expect someone who came to stay to take me out for a meal maybe just once, and/or bring me a small present like a nice bottle of olive oil or something.

It does sound a bit like she's just using you as somewhere to crash right now.

Probably because OP also spends a week for free at hers. It’s a reciprocal arrangement you idiot.

So she’s basically using you as a hotel. That would upset me too, but if your friendship is otherwise good then it’s difficult. You need to weigh up the pros and cons of your relationship and then decide whether to talk to her about how you feel, accept it and say nothing so you can stay friends, or simply not let her stay with you again.

Yeah that’s not good - is it because she is going with someone else or likes to go alone?

She didn't exclude you but probably thought you'd buy your own ticket if you were planning to go. You weren't in a position to commit, so she might have worried they would sell out if she waited.

I don't have a problem putting friends up, and I don't mind if they go out for a night without me. Maybe she thought you'd appreciate her not getting under your feet of she's staying for a few days.

@LoisLaneKent are the other friends people you don’t get on with? I could understand if she wants to go alone, but going with others while staying at yours for a week is a bit cheeky!

I would reply I can let you know near the time as I don’t want to commit to anything just now.

This is well put

She can’t be that socially awkward if she’s expecting to crash at yours for a whole week and not contribute anything!

just say "oh sorry, i have plans that day/week" and you can't stay, have fun at the gig"

Then tell her to bloody well stay with them!

She stays a week and doesn’t get you a £50 ticket? I think I’d be venting on here too! She’s not taking you out for multiple dinners/buying a big shop? How much would it cost for her to stay in your city for 5-7 days? I’d say that’s well cheeky and staying that long would make me sharpen some knives!

I would now try replying with 'ah, that won't work out this time as I've got lots on this week. Shame because I'd love to have gone to see That Band!' And see what she says.

It does sound now as if yours is the nicest place to stay and she's overlooking the rudeness of doing that while not planning to spend any time with you.

Other than the concerts how does it work when you visit one another? You've mentioned she catches up with uni friends so does she basically just use your home as a base? When you go see her do you do the same?

Is she going to the gigs with other friends that you are not friends with?

Surely if this is about actually going along this is easily solved by talking.

Friend: I have got tickets to see xxxx in 28 October, mind if I stay over?

OP: oooh I love xxxx mind if I come along?

If friend says yes, ask which area she's in so you can buy a ticket for the same, or say buy one for me and send me your bank details so I can pay you back. She may well say she'll treat you.

If it is about the money and she doesn't offer then say "well since you are staying with me perhaps you could get the tickets since I'll be hosting" but it does depend a bit on what hosting actually involves for you, how much you enjoy the visits and how much the tickets are.

I'm still not sure if she's going to the gigs alone or with others but this makes it sound like she is going with others:
she went to uni in my city (where we met) and uses the time to catch up with various people
And also going to other social meet ups with others and without OP. That would also explain why she's knocking around for 5-7 days at a time.

OP, can you clarify?
How much time does she actually spend with you, doing fun stuff, during the 5-7 days? Is it a decent amount of time which just doesn't happen to include a gig?
Or does she treat your house like a free B&B and head out every night seeing her cool mates and leaving you hanging around like a lemon?

If it's the first scenario then it may be that she's just in the habit of seeing gigs with a particular friend/group and it doesn't occur to her that you're irritated about not being invited as (a) she does plenty of other stuff with you too (b) it would shift the dynamic if you dont usually socialise with the other friends and (c) you've never mentioned that you'd like to join.

If it's the second scenario then she's a user and can get to fuck.
