Now Joel, don't take what I'm about to say the wrong way as I don't intend to diss you or anything like that.Did you pop her cherry?Your ex woman is a slag, probably had the transition during the bad times you mentioned. When she started to fix up, the attention from dudes probably made her happy & crave the attention. I know a couple girls who have told me they crave attention & that is their weakness. She hasn't got the ability to focus on one guy. This is a fail with some women & is a feature in a woman you should try to avoid at all cost! She's lost the ability to switch the attention seeker switch off.Come on, she was sexing you whilst she was in 2 relationships plus she's been exposed as doing stuff with another dude (who knows what she did with him & other guys who drawed her at clubs or down the street......).Your ex is trying to gass you up with telling you she wont cheat, but when a woman goes off a guy like that, it's usually because 1). She thinks there's no spark or the most likely 2). She's f*ck*ng/linking some other guy.Does she know you were linking this new ting? If so, she was most probably is really upset & thinking "f*ck, I flopped." /This new girl may be exposing your girl because she's feeling you & genuinely feel she doesn't deserve you, but has she done stuff to make you think she is untrustworthy, the ability to cheat? If she is like your ex, I advise that you avoid!IMO, your ex is a health hazard, I hope you have kept strapped with her tbh because if men are f*ck*ng her domless and she's disrespecting herself, YOU could be a victim.Remember, it will not be the same how it was when you were together the first time. All these negative thoughts will pile up and remain at the back of your mind. Imagine, 2 relationships = cheated. Once cheating is involved and is the reason for breakage then the relationship will not work. I have witnessed this, I have been through this, it will not end in happiness.Summary - She's trying to take you for a mug, don't diss or discuss the new ting to her either otherwise like she has tried to do, she will twist it so the new ting with think you dissed her. I think you should air your ex once & for all, don't keep in contact because women will try use this to try have a hold/power over you.
