I have known my friend for over 17 years. We message most days see each other weekly. We have been very close friends. We both left our DHs at the same time. She has recently got back from a trip to see an ex she knew 36 years ago in America. It all went well and she sent the odd photo. I dropped her at the airport. When she got back I heard nothing from her which is unusual as she always wanted to talk to me about him and usually messages loads and as I'd been her confidante I found that odd. After a couple of days I asked if everything was OK and I got back a reply about how she'd got back late, was then working and going out with her son. Nothing else and it isn't about being too busy not given her usual pattern of behaviour. I was the only friend shed discussed this relationship with in any detail. I'm getting ignored. Her new man is visiting her in July and she's going out to be with him for a few months later in the year. I'm now trying to imagine what I've done wrong. However I won't be spending too much time before moving on. I hate to admit she did this before and I let her back into my life.
