[40F] [30M] — I love him, but marriage may not be possible. Should I stay or walk away?

I [40F] have been in a long-distance relationship with my boyfriend [30M] for around a year.

We come from different cultural and religious backgrounds, and this has become a major issue when discussing our future. His family is quite traditional and has strong expectations around marriage, and his parents have a significant influence on his decisions.

He cares about me and I believe his feelings are genuine. However, he has also made it clear that he cannot promise me marriage. He is worried about the consequences of going against his family and the difficulties that our different backgrounds could create.

We've talked about what our relationship could realistically become if marriage doesn't happen. The difficult part is that there doesn't seem to be a clear path forward.

I don't want to walk away from someone I genuinely love simply because the circumstances are difficult. I'm struggling to know whether staying connected is giving the relationship a real chance, or whether I'm only prolonging the inevitable heartbreak.

I would really like honest advice from people who have experienced something similar.

Based on what I've described, do you think there is still a realistic chance of marriage, or am I holding onto hope for something that is unlikely to happen?

If you were in my position, would you continue waiting, or accept that it may never happen?

TLDR: I'm a 40F in a long-distance relationship with a 30M. We love each other, but family expectations, cultural/religious differences and uncertainty about marriage make our future unclear. Is there still a realistic chance of marriage, or am I holding onto false hope?
