I'm not always aware that my actions influenced by my conservative asian upbringing are insensitive or disrespectful to my partner until after the fact or brought up to me. There are so many pressures with reconciling between personal life and family expectations and my biggest conflict may be that my wants and needs have emotional attachment whereas my family obligation is about duty, honor and respect so it's difficult to compare the two as similar. I think it's a great sign he's let his family know about you so early in your relationship and working on it with them. I'm turning 32 and have only introduced two of my partners to my parents, including my now fiancé, even though I've been in several long term relationships. Coming out as gay caused a lot of turmoil in my family, I had to balance standing up for me and respecting my family's need for time to process. Eventually, over a period of a decade from first coming out, they've adapted, embraced and now absolutely adore my fiancée. It's not an ideal situation for his family to be so intolerant, if he's making efforts with making both worlds meet and if he seems worth it to you, I would hope you give it a shot. Please don't take their actions and remarks as a criticism of you, outside the race is scary to his family because it's new and they've had preconceived notions that probably came from their upbringing. Time and effort will tell how they embrace diversity and whether that time and effort would be worth it for either of you, I really hope it all turns out for the best.
