“just over a two months ago i was intruduced to a girl by a couple i know, started off texting and getting to know each other. when we first met it was fantastic, got along great , we have met up every weekend since. As we have got to know each other a bit more and opened up to each other, she has a few issues with one of her ex partners who she left for stealing from her. (she was engaged to him )
she is in the process of talking to him again and getting her stuff back, but now i feel on the outer with her , hardly talks to me ect. i feel ive done somthing wrong i dunno, it all started great ,told each other how we feel , she stated she isnt ready for a relationship 'just yet', which i respect and kinda understand. I dont no if i should keep trying to talk to her or just give her a break and wait till she gets in touch with me .”
Now, for this commenter's situation specifically of course, the problem's compounded by a lack of moving fast enough and attraction expiring. Those will cause the slow death of a potential relationship every time, ex-boyfriend or not.
But when her ex-boyfriend is in the picture, this is particularly exacerbated - because everything you have the might be good with her is less good, and everything that isn't the best gets worse.
Ex-boyfriends, in any way, shape, or form, are invariably bad news for any kind of relationship you want to get going with girls.
