My MIL lives overseas, 3hrs flight away and 4 of her 5 grandkids live in her city so she sees them regularly, has regular contact and is close. I've been with DH for 5 years, always a good relationship with MIL when we see her.
Our DD is 7months, MIL has only been to visit us when we have organised and paid for her trip. She barely ever initiates contact via messages or anything. I used to send photos and updates weekly but got sick of being the one to initiate.
For context, she is employed on an average wage and will go on holidays with her other children/grandkids but never makes any effort with us. We have always loved overseas but have moved closer to her over time.
WIBU to stop trying and switch off completely in regard to her? DH is very poor with contact anyway so if I were to stop it'd likely allastop stop except for bdays etc. I dont want to bring up her lack of involvement to DH as it might make him sad but I'm sick of giving and never getring in return :(
