I met a lady through an activity that our children do. We met up several times with our children and a couple without. Despite her numerous cancelling at last minute, turning up very, very late or rescheduling, I have always tried to be accommodating. I appreciate that sometimes life can be hectic and you don't always have time to socialize, especially when you have young children.
Her child then moved up to the next level in the activity, which meant that I didn't see her as regularly as I used to, but tried to keep in touch. She then stopped responding to my texts, but I thought nothing of it and just thought she'll get back to me when she has time. In the meantime, my child too moved up to the level that her child is at. Whilst I was looking forward to seeing her again, she just walked past me and sat across from me without so much as a hello. AIBU to expect a "hello, sorry I haven't responded to your texts. It's been manic..."
