@Suzette little girl 🙂
Rereading it I’m assuming lg is little girl? But anyway I don’t think your horrible just means you need to build some trust with the gf. Not sure if you know her that well but if you got to know her more and see her around your baby then maybe you’d feel more comfortable?
How long has he been with the gf? Has she had your little girl by herself before?
Sorry what is lg? It’ll help me to read this better 😅
