For context, my husbands family are extremely close and were brought up in a religious household. When we got together I knew they were all very close and it did take me a while to get my head around the hugs at the start and end of each family occasion (meals out, meet up for walks, pop in to the house for a visit) This was something a bit alien to me as, growing up, my own family were not very affectionate or demonstrative in any way, however, I did like the public show of affection my new family taught me. In particular my husband and his younger sister have always been extremely close which I've sometimes thought a bit odd and maybe a bit too much. I found out several years ago that, after DH went thru his first marriage break up and while he was spending a lot of his time with sis, he got really wasted one night (drink and drugs unfortunately) that he tried to snog her. She obv pushed him away and he was quickly brought back to his senses.
Focusing back on more recent events, him and his sister have been going on a lot of hill climbing days out. I cant join in due to lung issues(COPD). I have never minded this at all as it gives me time to do things I am more interested in. What has bothered me (and not sure if i am just being weird about this), is that they get pictures taken by strangers at the summits of these hills and anyone looking at the pics would think they were a happily married couple. Again, just something that has niggled at me but not really a big issue.
Today though, the three of us (she's a single parent and lives just round the corner from us) went for a local walk. We got a few miles in and his sis complained about some foot rubbing pain due to new walking boots. I mentioned my foot was also causing me some discomfort due to a blister forming on a toe. we were about a mile from home so DH offered to walk home and come back to collect us in our car. I nodded and said yes please that would be good but his sis said she was happy to plod on, so guess what we did? I limped along and mentioned 'I'm struggling, I thought you were going to go get the car and pick us up?". His response kinda floored me when he said 'I only offered coz sis was in pain'. What about my pain? AIBU to be pissed at this???
