Staying at my scottish boyfriend’s parents’ house

Hey guys, I’m not from the UK but my boyfriend is scottish and we have been in a long distance relationship for so long. He came and stayed with me and my family multiple times and i did the same, everything was fine.

But this time, since we haven’t seen each other for almost 6 months (longest time ever, because of my exams and internship) I will fly to Scotland and stay with him and his family for 2 months 😭 I feel so bad because I don’t want to discomfort anyone. I said this so many times to him but he says his parents are also okay with me staying for 2 months and they love me. they think i’m a lovely woman. Even if he says these, I can’t feel okay with it. But when I’m there with them, I help housework, I talk with them nicely, we spend good time with each other. And we never had problems with each other. they are so nice and sincere with me. But you know, still when you have someone else in the house you wouldnt feel as comfortable as usual. But he says no his mom is fine with it and he says i’m also part of the family.

I don’t know, in my culture if you go somewhere for so long it’s kinda rude and thoughtless. Btw the reason I’m going there for 2 months is we missed each other so much and he wants to see me as soon as possible, since we’re not used to not seeing each other for this long. Also I have a flight to America one-way, after that 2 months. And that flight is from Scotland as well. So we thought me staying there for a month and then coming back to my own country and 15 days later going back to Scotland would be a waste of money and not logical. ( I’m not living in america, it’s for education and I will stay there for 4 months. )

So what should I do? Do you guys think it’s really okay me staying there for 2 months? Or his parents are not actually feeling fine with it? What should I do to make his parents happier? I am so stressed, should I not stay there for that long even if his parents says they are fine with me? This place is the only place that I can have scottish people’s thoughts. I’d appreciate your answers. Waiting for your advices!

Note: When he comes to me he stays for a month, and when I come to him I stay for a month. So normally we stay for a month in each other’s houses
