I used to be really close with my in-laws.. I used to do lots for them, cooking, baking, shopping, gardening, putting a lot of thought into gifts and if I saw anything they’d like at the supermarket I’d get it for them etc., for 25yrs. Then husband left me and they didn’t even do so much as send a text, nothing. They didn’t even send me a Christmas card when I had sent one to them. I texted my MIL after a couple of months, she replied once but it was very bland. I know that he’s their son and loyalties lie with him, I’d never ask otherwise and I didn’t ask for an ongoing relationship, but after 25yrs, nothing?!
His sister and I were close too, I got nothing from her, she didn’t even reply to my texts. DH had a new girlfriend and SIL gushed over her (she wasn’t there in person as my DC had refused to meet her, that’s up to them, they’re in their twenties), telling my DS how great SIL thought she was and bought her a gift welcoming her to the family. My DS was furious, I’ve never seen him so angry, she can go fuck herself for all I care.
Long story, but Husband and I are back together after 3 years, PILs cuddled me and told me they really missed me etc. but there’s now a wall they’ll never breach again.
Sorry, I’ve made it all about me. I never get to say these thing in real life, lol, it’s a release. So, I don’t blame you, you’re not wishing them harm or extending any ill will, you’re just not wanting to see them and that’s fine.
