Hurts my husband (just needed to vent)

My mil doesn’t visit our children it’s always us going over to here house. She doesn’t even try to make an effort to come see her grand babies or son. I swear if I didn’t have Snapchat or Instagram she wouldn’t even ask about them. Then when we do try to go over she’s always busy (going to bars, going to friends houses, going to her dogs things). My husband feels disappointed and I feel so bad he’s hurt. Yes he’s an adult but so much has happened like her always going out partying leaving him with his younger brothers as a 8/9 year old with barely any food. He ended up moving with his grandma at 9 and I know now he can’t really remember much but she never really showed him attention either because she was always going out. Now he’s like why isn’t she all happy like most grandparents. Like mine my parents always come over and show them sooo much love and he sees that. She doesn’t even call or text to see how we’re doing or our babies. When we started dating and even now my parents and I talk basically everyday on the phone. He said he’s not used to it because no one really calls him like his parents. Like at least make an effort to come visit instead of going out to get drunk every single Friday/Saturday and Sunday. Like it’s a one sided thing we always have to go visit for her to see them. I feel like we’re forcing her or something it’s been a month since she seen them and she don’t even check to see how they’re going or anything. Then his dad barely makes an effort too. 😩
