Or should I just act like nothing happened?

So I was chatting with this girl on Tinder, we had a great chat. I asked her out, she seemed somewhat hesitant, but she was also out of town at that time. A few days later when she was back I asked her. "Have you been to this new place XXXX?". No answer. I figured she just wasn't interested in meeting up. I let it go, haven't thought about it until today.

Today, 3+ weeks later, she replies. Quite a long answer about the place and whatnot. And ends with "Sorry for the incredibly late reply."

(When you read this, I probably already have answered her. But it's good to ask for future reference.)

I feel like I need to call her a bit on the late reply, at least playfully. For me to wait a long time to reply would just seem passive aggressive and butt hurt. Or should I just act like nothing happened? It's not like I been sitting here waiting for her reply. But I feel if I let her get away with it, without even a comment, it make me look more desperat than calling her on it.

EDIT: I remember now, I think she actually said yes to a date, but flaked because she had to go out of town. (And she did).

You feel a need to call her out because in your mind you've given too much ground to her, and need to 'regain' it with some sort of a concession on her part. This is your issue, as far as I am concerned, not hers and I think tipping your hat to this with her can end up costing you.

I would explore more the belief you hold that is creating these feelings for you. But that's something you do by yourself, it doesn't involve her - rather its about your own growth as a person moving forward.

She is free of whoever she was doing at that time, she kept you in the wings, Your up slugger.

Update: Tonight that is ...

She came home with me, but massive LMR. Wouldn't even make out. So I just went to sleep. Either she's not that interested or I fucked it up at some stage. She did a lot of compliance tests, I bound to have failed some.

She was cute but not that hot, and slightly annoying. If she texts me I'll give it a second go, othervise leave it be.

I really don't think so. She seem a bit uncomfortable with her own body. Might be it. But not even make out?

She said "If we do that I will want more.."

Sounds like bullshit to me. I think she just needed a place to crash for the night. She lives a bit from the city.

I find it hard being assertive and going for what I want. I do it, but somehow I feel like I end up needy. When she left she said something like "Too bad you had to win the game last night (we played pool) or I might have given you some pitty sex".

Doesn't hurt to try again.
