Have you ever been in a relationship feeling the other person's not that into you? Why don't they just give up?

I used to be the person who wasn't that into them. However, I feel like I'm the one who's giving more and hoping more out of this relationship.

If someone's not willing to wait for the person they are with, does this mean that they don't give a fuck about them?

Is it weird or inapropriate that I feel they were looking for an excuse to dump me and now that they don't have it anymore they're angry?

Am I willing to lower myself for something I don't feel has a future?

Is it normal that when I'm with them everything's alright but when we're not I feel left out?

Too many questions for just a 2-week relationship. Isn't that a bad sign?
