Honestly when I just dated someone, I’d not see them more than 1-2 times a week. Sure 40 hours might not be a very high number of hours, but it’s still decent amount of hours. When my husband snd I dated, we’d see each other once a week or maybe even less. Too busy and tired for more

Any reason in 6 years you did not make relationship official?

Most young women move on after few years if there is no permanent commitment. Don’t know about her parents. It might be just an excuse why she doesn’t want to see you much. Real reason might be something else. And it’s possible her parents don’t approve 6 years of dating.

I see that she was hinting about marriage telling you that she can’t live with anyone unmarried or cannot have children out of wedlock, and you still didn’t think of proposing. It doesn’t take that many years to know if you want to marry. I think that’s the true reason why she moved on.

Let her go. At 27-28 she might want to start looking for commitment, marriage and kids. Not dating someone for years
