Hi Perna, to answer your questions
Yea, I got to meet his brother once I think, but his brother was so quiet I didn't really get to know him or even talk to him actually. And I don't think his brother has a girlfriend. Both of them seem to be really devoted to their family. Anyway, I think he's allowed to go out with his brother. I think when they go to the beach, it's just them two.
Also, we live probably about 35-40 minutes away from each other. We went to the same university so that's how we met. We were in the same major. We met later near the end of the college years in then end of junior and on to senior year. So while we were still in college, we lived together during senior year. I still had my own apartment just so I can put my stuff and come back whenever. So yes, we do have our lives together, dealing with stuff together. But it was always just us two. I still hang out with my friends, and spend time with my family. He still hangs out with his friends, and his family. We just do it separately 100% of the time, even on big holidays. So it's kinda like, when we're together we're all about us. You wouldn't see us separated at all. But once you add in family and friends, then he's never there. And since his parents don't know about me, I'm never there at his events either. I don't know about his friends, maybe they don't like me? They used to invite me to stuff in the beginning of our relationship. Then now they don't anymore? And when he's out with his friends he doesn't invite me along, so I guess they may feel weird too if they invite me haha.
I don't know about his parents and how strict they are, but they just seem really strict to me so maybe he's not allowed to go out at all except with his family or guy friends they know.
