Hopefully this doesn't sound trivial but just wanted some thoughts about this... On Sat night we went for a rare night out to the pub to celebrate the birthday of a mutual friend of my brothers and mine. It had been my birthday last week and we always used to celebrate together. My db and sil arrived a bit later than us - DH and me - the pub is quite small and I was at the end of a group of tables. My db and sil sat opposite me but didn't really acknowledge me or say hello. I haven't seen them for about a month and although SIL had sent me a text on my birthday I hadn't heard from my db. We tend to see them at my parents house fairly regularly but they seem to do this thing of being friendly at my mums but then barely acknowledging us when we're out ( we have mutual friends and often go to the same stuff) they then got up to leave - my sil came over and said - oh didn't have time to chat and then my db glanced over and mouthed 'see ya' . I then said something along the lines of hoping to see them tomorrow as would be visiting my dad who lives near them. They then left and I just felt really upset that my db hadn't even bothered to say Happy Birthday or ask how I was - never mind no card or present - we do presents - eg last year my sil sent out a text asking for money for my db birthday as they were going away for a long weekend and wanted some spending money - which I duly posted off to them and which my db didn't mention again or say thank you for. I just feel that if he can't be bothered to say happy birthday to me - what is the point. If you're wondering why I didn't go over to them - I usually do - and try to start conversation - but I was a bit stuck between people and also thought I would see if they would make effort - which they didn't - but spent time chatting with various acquaintances from the school gate. . Our fam set up is a bit weird - my parents - esp dm - are difficult and I know he has a hard time with her - as do I. There is a bit of history here - we used to be quite close and then he seemed to turn against me - I have no idea why and I have tried for the last few years to rekindle that - but it hasn't seemed to work. Should I just accept that he doesn't really like me and not bother anymore or tell him how upset I am?
