I probably am, but DH's sister has really started to irritate me.
We got on very well until DD was born last July. Since then, whenever we see her, SIL tells us how upset the PILs are that they don't see more of DD. In particular, she says that PILs are upset because we see my mum and dad more often. We do see my mum and dad more, mainly because my mum will babysit whenever we ask and will generally come round if she is free, cook dinner, do laundry, babysit while I have a bath and leave again whereas PILs need to be entertained and like to keep to their routine.
DH is not very close to PILs and they have never spoken regularly. He would quite like to see them more often but works very hard and doesn't really get round to phoning them much. They haven't phoned us since Christmas although we have gone over to see them. I have said that PILS are welcome to come over whenever they would like and just to give me a call when they are on their way so that we can be in - they haven't taken up this invitation.
PILs haven't said anything about wanting to see us more and haven't done anything about trying to so I kind of think they don't really mind. BUT, I am a bit annoyed about the suggestion that we should be seeing less of my parents to make it 'fair' and I now feel a bit fed up with DH's whole family which doesn't exactly encourage me to make an effort to keep in contact with them which is a bit awkward because I do actually like my PILs!
Sorry this is so long, anyway, AIBU and generally any tips for dealing with this would be very welcome!
