Let me explain something I’ve learned about in-laws because I was desperate to be part of ex-DH’s family, since he kept me from my own, and I don’t want you to be hurt like I was. But you are labouring under a lot of false assumptions about what a “normal family” is.
It doesn’t matter if you have no family. It doesn’t matter if you had a rough upbringing. No one is going to treat their son and DIL the way they treat their daughter and SIL. They have a mother-daughter relationship established over a lifetime, and you don’t, and the fact that you’re hurt by the loss of that relationship with your own family does not mean they will treat you like a blood daughter (cue 100 people disagreeing with me, but I still think that’s the exception, not the rule). It hurts, it sucks, but it’s true. If you were to divorce DH, you’d likely never hear from them or see them again. When exDH replaced me with one of my friends when I was sick, it was a real shock - I was betrayed by my DH and one of my closest friends, and his family, especially his aunt who I thought was honestly one of my friends, couldn’t wait to embrace her and couldn’t have given a shit less what he did. Yes, occasionally you see these posts on here where people say their in-laws have supported them when their DH had an affair, but it’s not necessarily the norm, and that support rarely lasts through divorce.
I wouldn’t say they’re “shit grandparents.” They see and interact with your children, and they’re giving you money to help. I realize you’d rather have an involved family than the money, but sadly, we don’t get to choose in life. They’ve already made it clear that their time and energy are reserved for their daughter and her children. If you can’t rely on them (and you can’t, I assume - would they cancel their plans if you gave birth two days before they leave and either you or baby is poorly? If you don’t know for certain, ask them), then you have enough time to make a choice, and I figure you have three:
- your DH will have to stay home with the children and you’ll either need to go to the hospital on your own or find a friend to be your birthing partner. I imagine this happens every day in large maternity units. On One Born Every Minute, there’s a woman in your situation at least once or twice a season (and one woman, a recent immigrant, who had no support at all, not even a partner). I just watched a woman’s DH and 2 year old take her to the hospital and then he went back home with the 2 year old and she stayed to give birth.
- Someone, likely another mother with young children (since you said that’s all your friends) will have to watch the children; your husband stays at hospital with you, but needs to pick the children up if you’re in for more than one night.
- You use the money from the ILs to hire in help for a few days from a registered temporary nanny website. They have several that specifically advertise for maternity or night nannies, depending on where you’re based.
You need to have a plan for all eventualities that doesn’t involve relying on your ILs; on any given day, something could happen to you or DH or one of the children, and it sounds like you don’t have any emergency plan of who would care for your current children temporarily.
I wish you the very best of luck. This shite is difficult, especially when your own family have cut you off (or you cut them off) and you just want a family like you see other people have. I would recommend appreciating what your ILs are willing to give, and focusing on gratitude for that instead of anger over wanting more; it has nothing to do with whether they’re right or not, but if a situation is unlikely to change, the only person you upset by being angry over it is yourself.
