<human>: Can you succinctly summarize the text in 1-3 sentences?

A girl I liked broke up with her boyfriend and got with me about a day or two later. we dated for a week before her ex went to her hoping for a second chance. she says she didn't "choose" cause she couldn't say no at the time and that it was "complicated. before all this and now we were and are VERY good friends,we talk all the time and about everything. sometimes when im  talking to her ill pull a dick move and do something like "why does this concern me Im not your boyfriend" or "oh yeah that sucks....remember that time you chose X over me? that REALLY sucks" I cant help but do this cause it makes me feel better. Do I have the right to keep doing this and why do I feel good when i do dick moves like that.
