I'm the breadwinner in the house, i went back to year after a year maternity leave and DH became the SAHD for 5 years due to my earning power vastly outearning his. All stable, fine, wanted/planned. I work Mon-Fri normal office hours, but WFH 99% of the time so am around a lot/only occasionally travel 1-2 nights away every couple of months. We have 1 DD who was very much wanted and planned.
I'm struggling with elements of my relationship with her, and how to navigate it/or if i should be doing anything different. It seems to be getting worse, not better.
e.g. She left something she needs for school in her room today so I went to look for her, and couldn't find it. I went back to tell her i couldn't find it, and my husband heard her saying "God, mummy is so stupid" on the way into her room. He told me afterwards because he thought i'd heard it (i hadn't) and told me to not take it personally. He told DD to apologise for saying that and to come over and hug me to say sorry (i had no idea what was going on as I hadn't heard it).
I'll be honest, I'm sitting a bit upset and this happened over an hour ago! (And it was on the back of telling her this morning that we've booked a really amazing day out next month that she'll love - a very expensive awesome trip that she seemed so excited about). It made me feel really awful on the back of a few other things she's said/done recently.
She often runs over to hug and tells DH "I love you daddy" when I'm standing there, but she often looks at me first before saying it (even when it's not practical i.e. he's carrying a load of stuff in his hands!).
When we mentioned that she couldn't do something earlier this week, and my husband said something like "I'm sure some Daddys would let their kids do that, but i won't" she said "I'm going to go to a shop to see if they sell you" and when we asked what she meant, she said "actually I will go to a mummy and daddy shop but i won't replace you, i'll just buy a new mummy". She was looking at me when she said this and my husband pulled her up on it by saying it was quite a mean thing to say, and we left it there.
I don't know what's going on here. I'm present, i do a lot of her personal care (e.g. I'm the one who bathes her, does her teeth morning/night, helps set out her things for school the next day, practical basics). DH now only works part time so is with her between 3.30pm-5.30pm daily. I know "my" part of duties interrupts her a lot i.e. she gets TV time between 5pm -5.30pm daily while he makes dinner, then when I come out at night, she has to turn off the TV and we wash hands together to eat etc.
I used to think these were just cheeky things designed to test my reaction, or that she'd grow out of it, but this has been going on for about 2-3 years now - it really started happening when she was about 4 ish (not suddenly or explainable).
I don't know how to improve things from here, or if i should be more deeply concerned about all this - or if it's just an age thing/testing boundaries?
