Hello. New to the group. I need a place to vent, so I apologize for this being long. I am a bio mom to a 7 year old girl and stepmom to a 13 year old boy and 15 year old girl. I've been in their lives since they were 4 and 6. Stepson is a wonderful kid, him and I have always got along great. Stepdaughter, however, I cannot stand. She is legitimately a compulsive liar, lies about anything and everything. My husbands family feeds into her lies and constant bullshit. My husband and I actually split up for about 7 months because she told him I would call her terrible names and whatnot.
