Ok, so I'm looking for some ideas as to whats going on here.
I've been best friends with this person (I'll call her Lisa) since college. We just clicked immediately and have been super close ever since. We dont live near each other now but even though we dont get to see each other often, we are always texting back and forth making each other laugh, sending jokes, messages of support etc. We always share deep feelings, its always been 100% reciprocal and have always supported each other through difficult times.
Over the last year or so, I've felt some weird but subtle shift happen. I will text Lisa as normal but often my messages are read and then not replied to for weeks (if ever). Nothing has changed- her life is pretty much the same, we have never had an argument or even a cross word with each other so I am baffled as to why this is happening. I've asked her if everything is ok and she says its fine, no problems. I dont text her excessively as I am busy too but I'm finding this repeated lack of response odd. Ive noticed she also never remembers my birthday, even though I always make an effort for hers.
It was recently my birthday and I asked her if she was around to meet. She was oddly vague about it and said she couldnt do that weekend. Fine. No probs, we arranged for the weekend after. Then I see on Facebook that another college friend had tagged her the weekend of my birthday as they had arranged with two others to all go out for the day together. I liked the post and then she sent me a flurry of whatsapp messages saying "oh I'm sorry I didnt mention it, it was an impromptu get together- you know you are my bestie" etc etc... I let it go but it nagged at me as it obviously wasnt an impromptu thing and I found it odd she didnt invite me as it was my birthday and I also know and get on with these college friends.
Since then she's been distant and taking weeks to reply to me, yet still telling me she adores me and I'm her best friend. I'm so confused- she is saying one thing but her behaviour tells me something completely different.
What do I believe? any thoughts, I really dont quite know what to do- carry on as normal or back off as to be honest, its making me feel a bit shit continuing to contact someone who either doesnt reply at all or just leaves my efforts to meet up unanswered for weeks on end.
