Mmmm, well it's more of a cultural thing I think. I'm from North America, he's from East Asia. In the area we live in now, it's pretty standard that people get engaged quickly. I've told him about my customs in my home country, and he's willing to wait it out as long as we need - I did tell him I needed more time until we get married.

My therapist has reassured me that this relationship is GOOD for me, and that it will take time to learn what love is supposed to feel like, as opposed to lust - as other commenters have pointed out. I didn't want to turn down the proposal and make him think that I was rejecting him - but we did have a conversation afterwards.
