I need advice

Hello everyone it’s been a long time since I’ve posted in any groups on here. I’m staying incognito for many reasons And also just in case my BD may have other bms in the group or anything I don’t want them knowing who I am. BUT ANYWAY my kids fathers has been in heaven since 2019 His family doesn’t help at all with my child they don’t call check on her NOTHING , when I confronted the younger sister (daughters aunt) she said it’s because I’m always talking about my deceased bd who btw was my bf when he passed but to me that’s not a excuse on why y’all aren’t involved in the kid y’all claim you loves life. They choose to be there for only 1 out of his 5 kids I cut them all off but parts of me wants to keep trying even though I’ve tried with them for almost 11 years
