DH came home from work on Monday evening and as usual and came and gave me a hug/kiss when he walked in, DSD8 was with me in the kitchen and he then gave her a hug and kiss and she responded with ew get off me dad I'm not 'bluenotebook'. He responded with what do you mean, her response was you are treating me like 'bluenotebook' he then said I always hug and kiss you which he does. It was a really off hand comment and not sure where it had come from as he is always very affectionate with her, as am I, I have a lovely relationship with her.
So since then DH has been completely weird with me, has backed off from me, hardly even come near me and has been moody with me. I had noticed the change in behaviour and didn't think anything of it at first and put it down to him having a cold and being a bit under the weather. Then yesterday I was sitting on the sofa with DSD cuddled into me watching telly, he came in said he was going out to the shop and gave DSD a kiss and then just walked out and I sat there and thought that was weird as he would usually give me a kiss also. Then at tea time we sat down to eat but he didn't sit in his usual seat next to me, he sat in a seat next to DSD (we all tend to sit in the same seats every meal time, not sure if this is weird or not!). We then went out in the evening with the kids and I felt like he was almost trying to exclude me.
Now I have no issue with him wanting one on one time with his kids without me there, I think he should have that time with them and I do encourage him to and I am happy to step back from family activities so he can, nor am I particularly needy in that he has to sit by me at all times etc, I'm just trying to give examples of how he has been different with me and I really feel like he has been this week and this is the only thing I can think of maybe why.
I don't know if I am BU to think that this comment from DSD has affected him or if its just me overthinking.
Would really appreciate some perspective and any advice on how I can support if it has bothered him.
