Should I stop trying?

[Kylar]

So there is this girl I use to work with (she was fired) that I'm kind of hung up on. I'm 24, she's 21, were both single, but she hangs out with an ex a lot (I know huge red flag).

 

She is always quite flirty with me, has even told me she likes me and flirts with me. I've always been flirty with her, and often find myself doing things for her which is a little unusual for me early on.

 

On new years I'd asked her to come out with me, very directly that it was an invite to be with me on new years. She agreed but said she had to bring her roommate and her roommates boyfriend. While I wasn't a fan of that, I agreed since it didn't effect it much either way.

 

At the last minute when I said i was going to come by and pick up her, her roommate and her roommates boy friend she said shed just drive since there was 4 of them. Now I'm not amazing at math, but her and her roommate and her roommates boyfriend equals 3, so naturally I inquired who the fourth was.

 

After a lot of hesitation she indirectly implied it was her ex. Obviously she would have known this would be an issue for me since she didn't just say it. We then had a short exchange over text that went something like this:

 

Her: So are you there yet?

Me: No.

Her: Well are you coming?

Me: No lol.

Her: Wtf why not?

Me: I invited you out on new years and your bringing your ex boyfriend.

Her: Thats not fair, you know he's like my best friend.

Me: It's not you I'm mad at its myself.

(I said that because I knew I was an idiot for trying to peruse a girl who still hangs out with an ex regularly)

Her: Omg wtf

 

Anyway I went out for new years with a friend instead, had a great night and figured I'd never talk to her again. We went from texting several times a day, to not texting at all. I did miss her, and I was thinking about her a lot, but I figured it was for the best.

 

About after a week she texted me and asked if I was still mad at her. In the short exchange I explained I wasn't mad at her at any point, but I disappointed by the situation. She told me directly that she didn't think it would be fair to get involved with me right away since she still had feelings for the ex, but hadn't talked to him since new years either (my guess is they fought cause of me).

 

For some reason I can't get over this girl, I've been on dates with other girls since I've been talking with her, and on new years I even hooked up with a different girl. But my heart hasn't been in any of it. I really like her but she always seems so distant when we text or call, but in person its always some of the best times of my life. The odd part is we haven't even kissed yet let alone hooked up.

 

I just don't know if I should keep perusing this when its starting to seem like she isn't at all serious about it. Opinions?
