I have a friend (of about 6 years). We have spent much time together and enjoy each other's company. I can rely on them about 90% of the time. Said friend can sometimes go on a hiatus and not want to see me/decline any suggestions of meeting (e.g. just for a quick coffee) and their texting pattern will change. Friend only behaves like this with me, though; during their hiatus, they will still make time for other friends.
Said hiatus is currently happening and I haven't seen my friend for a month or so but they messaged me today and after a bit of texting they've asked for a favour (because I have a car). I haven't agreed or straight out said no (but I most likely will decline) to the favour as it just rubs me the wrong way a bit, I haven't seen them for a while and now when they want to see me it's because they are asking for a favour. If this was any other friend I'd probably say yes.
Majority of the time, my friend is reliable which is why I'm a bit unsure, however, I have no issue with saying no but just want to know if I am making this into something it's not.
Thank you for reading :)
