Dp used to have feelings for this woman he used to work with and she had feelings for him as well. This was about 4 years ago before me and him got together. They never dated but it was definitely mutual feelings.
A week or so ago, she added him on Facebook out of nowhere and then posted a rather...suggestive Facebook story of her in a bikini. They’ve not been in any contact other than becoming Facebook friends.
However I’ve just discovered that about 10 minutes after he viewed this image, he searched for her on Instagram and requested to follow her.
AIBU to think he’s looking for more with her? As I admitted, it is very juvenile but can’t shake my concerns.
