So, this question is a continuation of this post
open-relationship-got-hb-love-hb-reject ... 82608.html, i'll resume it quickly.
I'm in a open relationship, my girlfriend lives miles away. So i started dating another girl, we 'got together' like 3 weeks and then she travelled abroad. When she came back she stopped texting me and was really cold. I got mad (i know) and asked her why she was acting that way. The conversation was inconclusive, and we ended having sex one more time some days later (i invited her to have dinner in the same day i made the invitation

), when she told me she missed her boyfriend (whom she broke up A YEAR AND A HALF AGO). This was the last time we were together as mates.
Since then - except the day after we had sex, when looked like she was going back to talk to me nicely - she's really cold and distant and etc. One week later i called her to come to my home in that same day and she rejected. Maybe i was a jerk 'forcing her to my life', and then i told her i would stop annoying her, to which she answered that she liked the idea: this was the begining of the plan to ignore her to create attraction. Until now it's not working HAHAHAHA and i think you guys may have tips for me, even if it's to leave this girl.
Ok, so it's been almost a month since our last date. An important detail of this post is that she told me, back when we were dating, that she didnt go after the guys - a statement that i think is true, since she was laid back when we dated and just started to come after me some days after i kept on talking to her and etc. So, my doubts:
1 - Do you guys really think that there are girls that really don't come talk to us, even if they're attracted? Im no assuming shes attracted to me, but the contrary. Its just a general question.
2 - We're like job colleagues, so we see eachother like once a week. The 'ignoring approach' is absolute or is it more like acting normal? Cause today i saw her and i went to talk to her, but im a normal way, like friends (problem?) Interesting to note that even me behaving normal she was still more like this cold bitch hahahaha. By the way, how would you guys act in situations like these?
3 - Based on what i told you, do you think i should try to invite her to have dinner or something like it? Since "she doesnt approach the guys" and i kinda screwed it up too early by saying id stop annoying her, is it a good idea to call her to a date? She's been giving me nothing but indicators of disinterest.
Thanks in advance.
