IMHO, compmom understood it correctly but some others did not.
As regard to the “why” mentioned by HarvestMoon1, it is because OP consciously or unconsciously wants to show (maybe wants to convince himself and her) that he cares very much for her because she cares so much for him.
The way a couple in Asia shows their affections to each other could be quote different from the way in the main stream culture here; it could be perceived by many as being too clingy to each other. At least this is my take on this (of course, I belong to an old generation. But I still think I likely know how it “works” there better than most CCers (I may be a little bit arrogant to say this. But I have been living in that world in the first half of my life, i.e., 3 decades, there and have learned from sometimes painful experience.) I knew of a case that one of the couple similar to OP’s case was unpleased (almost quite upset) when the other was not “clingy enough” (using the standard here) which was perceived as “not care for each other enough.” Some may think this is strange.
Compmom is right. The only potential problem is her parents’ opinion. If this is not handled properly, it could bring pains to all parties involved. They need to sort this out eventually (But it is likely not now; it will be in the future, for example, when OP (especially) and his GF succeed both academically and career-wise, either in the US or back in your country of origin. Just showing affections to each other will likely not change her parents’ opinion about OP. Thus, no matter whether OP’s GF attends the same college or not, if OP really cares for her and she cares for OP, both OP and his GF had better work hard and succeed. (OP and other CCers may or may not agree with me on this. But I said this with a good intention and genuinely wish both of you, OP and his GF, well.)
