So this is regarding two attempts I've had so far in asking girls out, both of which go to the same College as me.

The trend is the same, the first girl I spoke to for about 30 minutes, and got her number, and the next time I saw her I decided to walk her home. She was acting very flirty with me, bumping into me as we were walking etc, I looked her straight in the eyes and told her I'd like to take her out on a date, she said she was free next week on the weekend, so I set a date for 2 on a Saturday. During the following week I saw her a few times and she was always smiling at me. I didn't speak to her at all or text her during this period.

Fast forward to Saturday, she's a no show, I wait 10 minutes and then give her a call, she picks up, hears it's me, and puts it down. She then texts me asking what I wanted. I told her we had a date for 15 minutes ago, she sent a few texts being like 'oh I'm so sorry - I forgot I thought it was tomorrow', I replied telling her I was busy tomorrow and she said 'lets do it next week then', I told her I was busy anyway because I don't really want to go out with a girl who would stand someone up.

The second girl I first spoke to for about two hours, and got her number. I didn't play as minimal with her, which is bad, but I'd say this girl was even more interested in me. I asked her out on Thursday and set plans for today. She grabbed my arm and said yes, so I told her to meet me at 1PM on the Saturday.

Then, yesterday, out of the blue, about 5PM, she texts me 'Hiya. I like you but I'm just not looking to date right now. If you want we can hang out sometime as friends.'. Again, I told this girl no, and that if she changes her mind she should let me know.

Okay, so the main issue is of course, with both of these girls, I didn't make a date on the spot as soon as I met them, I just got their numbers and waited for an opportunity to talk to them face to face to ask them out. However, I'm really struggling to understand WHY they would both flake like this, I'd say I'm a physically very attractive guy, but oscillate between being socially awkward and confident

Any ideas on what I did wrong? How can I improve?
