I have had quite a difficult relationship with my brother. It is pretty one sided. I get the impression if I did not get in touch he wouldn't either. I do it mostly because my DC and his DC (cousins) get on very well together. However, arranging anything is often tedious and drawn out and it feels like he does not want to meet at all. Examples are me asking him when he is free. Him saying 'maybe' a lot to dates even up until said date. Many times we have agreed to a date and then he has cancelled because he is meeting his friend or going somewhere else instead. When he has agreed to meet up on a certain date it is usually on his terms. He'll tell me when he is arriving and where we will be meeting/going and won't even bother asking if that is OK. If I object he'll say something like 'OK, you do your thing and we'll do ours'.
A recent example is this weekend. It was my birthday recently and after many 'maybes' he said he was coming this weekend to celebrate. I've just received a message saying he has booked a table at x restaurant at x time and if my family would like to join? I think this is a bit off because the whole point was to spend time together and celebrate my birthday but it seems he is doing his own thing now and asking me as a last thought. This is quite usual and I'm constantly feeling things are very 'off'. It also takes the enjoyment out of meeting although the kids always have a great time. Is this behaviour off? What can I do?
