So, I met this girl at a bar.

She came with home with me.

Next week, I hangout with her again at a club.

While we are at the club, this guy starts chatting with her, tries to kiss her and then later gets her number.

I get mad and storm out of the place. She follows me and tells me she just did that so he will go away.

She came with home that night..Had breakfast..left next afternoon and she asked me when we can hangout again. I told her about myself (I told her: I am pretty new to dating but have been going out a lot and madeout with a girl last week but I like you..)

After that she has been texting me how I am awesome and we should hangout again etc..

On a phone call with her, I casually bring up the fact that she gave number to a guy. She says again the same thing that she goes to clubs just for music doesn't care about giving umbers etc.

Later, I actually run into the same guy and he tells me that she made out him and he took her on dinner (shows texts convos to prove it).

Now, it seems like 1) I shouldn't be mad because the default status of all relationships nowdays is "non-exclusive" but 2) she lied to me about why she gave the phone number. If she was honest, I could have tried to recalibrate but was shocked when I found out like this..

As I said I am still pretty new to meeting girls and I was getting pretty emotionally invested into this girl as she was nice. For now, I have blocked her number and deleted all convos as I was getting kinda getting weird and tend to drunk text/call.

Also, I am looking for a girlfriend and this kind of behavior kinda bothers me a little (I want to be old fashioned and believe in romance and love).
