I'm having a bit of a weird reaction to a change in family circumstances and I think I need some help to unpick why please. I have an adult DSD, been with her dad since she was 3 and always had a good, close relationship with her. She's recently had her first baby and is asking fairly regularly for us to babysit. All fine, except it's not. I can't explain why but I feel really negative about being asked, like it's a massive imposition even though rationally it really isn't. I actually feel angry when she asks and it's causing rows with DH because he can see I'm not keen.
In my defence (kind of) we are busy, DH works really long hours and weekends are precious. We are also working through some relationship issues and had been (prior to DGD's arrival) trying to prioritise time together. DH also has form for changing our plans with no discussion with or consideration for me and also for taking on too much because he doesn't like saying no (to everybody other than me at least).
So, his instinctive response when asked is 'yes', which I completely understand, she's his DGD and of course he wants to see her. But my gut reaction is the opposite, all I see is whatever plans we'd made going out the window, along with any progress with the problems between us and it just makes me so angry, and then ashamed because she's my (step)DGD too and I shouldn't be reacting like this to seeing her.
It's making me miserable, I feel like the bad guy (and I probably am) and I hate that. I think DH is a bit baffled, it's really not like me to react like this and he is (understandably) seeing it as a bit of a rejection of DGD. I don't know how to get past this, we argue pretty much every time DSD asks and seem to be coming from such opposite perspectives I honestly can't see where the middle ground is.
I need to work out why it's provoking such rage in me, I am perimenopausal so maybe that's part of it but it's just such a strong reaction and I can't seem to control it. I'm sure a big part of it is that I feel our issues are getting sidelined (again) but there's little I can do to change that so I need to find a way to change my reaction. Help
