@Anita – Thank you for your kind replies!

Regarding this:

But you “couldn’t take a decision” perhaps because you thought love should conquer all, that you will be a bad person if you end a relationship for financial worries (?)

Yes! It was that concern and thought itself that am I being materialistic which made me think about the situation a lot.

You can talk to D about replying to your messages when he is online: ask him what is behind the timing of his replies to your messages. The more information you have, the lesser your anxiety.

I am not sure if it would be a great idea as it might seem like I am trying to intrude in his privacy.

Best,

Kate
