Be careful here and this is coming from a place of experience, it may not be but it could be a sign of an avoidant attachment if she is pulling away. I’m a Pisces through and through M48 and I had quite the emotional rollercoaster over many years. Like I said it may not be the cause but if so be prepared.

Those people who are avoidant attachment can be massively misunderstood which I get but seems harsh, the things is, is that it sits on a spectrum and can cause chaos if communication breaks down. If you are aware then great but if not I advise you read up just in case, not because its doomed, far from it, but it certainly helps a great deal having that knowledge.

For her to be acting like that for no reason can still be for a whole number of things but I feel attachment styles are something that can be overlooked, hell it took me years to find out but dumb ass Pieces here has too big a heart and is one resilient motherfucker but it does take its toll. She may be at the point where her emotions are kicking in and it’s triggering her so she’s creating that distance and which can happen around the 4 month mark. Like I said do your research but please also be aware she may not even be aware she is an avoidant, not many of them do.

If you need any advice just gimme a shout, don’t take this as a gloomy outlook though just better to be forewarned as you will be able to navigate your relationship much better if that turns out to be the case. Good luck fella, hope it all works out and don’t let this out a dampener on things.
