Yeah that’s sketchy. Unless they live in another state....after a year you DEFINITELY should’ve met some of them. He’s either not serious about you or hiding something. I’d have a serious talk
That happen to me & I drive by his house to surprise him on his bday and he was getting out the car with his wife n kids with pizza. I waited 5 until they went in then I went inside before he locked the door.
To make story short the whole time I’ve been dating him she’s been living with him.
