Mom's Moving Out Again: Is It For Real This Time?

got a message from my mom this morning saying she's planning to move out of the family house. she said her and my dad haven't really been a couple for a few years, which isn't that surprising really. the problem is I'm not sure how legit this is. She's told me so many times throughout my life that she's moving out and they're splitting up and so far it hasn't actually happened. I'm also not sure what my dad knows of this plan she has, she could have just decided and not talked to him, so I don't know what I can ask my dad about. I just hope this doesn't turn into even more pointless drama in my life. I'm already so overwhelmed.
