It makes us proud to see what got our girlfriend a gift that makes them happy and feel more beautiful. We're not trying to impress you. If it felt like a chore and got no joy out of it, we wouldn't do it. Do you enjoy when your boyfriend gives you jewelry?
Depends on so many factors. Se I prefer to put more thought into a good present, but I'd give my girl a ring that says hey we're together in the long run and whenever you look at this and I'm not there always use it to remember I'm probably thinking about you and missing you too:D
