Been on a few dates with a guy. We are the same age, our kids are similar ages and we both work full time. We live 5 mins apart. He has his kids 50/50. He’s been out of the family home for a year and in a week he moves into a new flat. He’s usually really good fun but tonight he seemed distracted. We kissed etc in his car on the way home and then he got odd again. He then out of the blue said he’s got a busy couple of weeks coming up after he asked me what my plans are next weekend. I feel this maybe is a bit of a brush off? Or am I being over sensitive?
