I think there is something more going on though.
Basically, if a man doesn't want a woman but she is chivvying the relationship along and he's meh about it - then you get the scenario whereby she wants to press go and he isn't bothered, until someone comes along who he IS keen on.
Then you get the whole 'he never really loved me, he looked at other women all the way through, he isn't a very good quality guy, he's lazy, he's not good enough, but I wanted it so I chivvied it along and now he is leaving or I've had enough'.
I've done it myself - found a man, thought he was great, found him a job, helped him dress better, helped him in a hundred ways only to realise he wasn't that interested and he wasn't that good - it was me that wanted it and pushed it all along.
So yes, to me personally - if a man loves me, he will want to ask me properly to settle down. If he isn't that interested in me or our lives don't really align very well, he won't be that keen.
I wish I had been less keen on certain men and not wasted my time tbh. I wish I had sat still and waited to see how keen they were - do they text, do they make plans, do they show their interest or is it me? And when they do show interest, I still wish my standards had been higher at times, not that they were bad men, just that they were not right for me personally.
