So I have my husband's sister telling me that my husband is losing his damn mind and saying he is gonna come when our baby is born and take her from me. She said he has been trying to hook up with a ton of women while he has been in North Carolina and I just talked to him and of course he said that everything she said is a lie and that she is the one who is losing her mind and doing drugs and all this bs. Like WTF?? Lmao. I don't know who to believe but I will tell you what, if either of them are even partly telling the truth, then neither of them will ever be around my daughter until they both get their shit straight. Lmao. Wow.
