He still hasn’t told his parents

Okay so I posted a few months ago after going out with this guy for 2 months saying that he still hasn’t told any of his family about me and that I find it really odd, and I got lots of response saying I was being silly and overly psycho about it, it’s almost 7 months and no one knows on his side that we’re together. He’s met all my family, makes out we’ve got a long future together. Also! His home is 3 and a half hours away from mine.... He goes to uni only an hour and a half away but it’s easy by train and I don’t mind the travelling..

not to mention the fact that he also talks to another girl everyday, they have a streak of like 4 billion and they used to date a little and now they’re just really good friends. She lives near him. He said he wasn’t attracted to her and didn’t want anything but that they didn’t want to lose the streak, so they still talk...

I trust him so much and he’s my first ever love.... but something fishy is going on and I can’t help but be jealous of his friend and still completely agitated by him not telling his family about me at all.... am I being silly?
