Somebody please stop me from moving my little family in with my boyfriend

It seems like a great opportunity for me because i no longer wanna live here with my brother. He fukin chewed me out this morning for not coming home last night but I told him leading up to the day that I was gonna spend some time with my boyfriend yesterday. And now he’s telling my parents that I was being an irresponsible mother again. But me and my cousin agreed upon her watching the kids after 4 and I kept calling to check on them and she told me everything was going fine 🤷🏿‍♀️But I’m just completely done with my brother anyways. I mean, I appreciate him letting us live with him until I got my shit together but I can’t stand him telling my parents lies and making it seem like I was abandoning them 😭😭😭😭😭😭 I hate when he uses that term and he knows it
