i think i was somewhat like your ex's. my ex did tell me about stuff that was bugging her, but i ignored it or i'd change for awhile and then change back eventually but i had my own reasons. i may have turned somewhat boring... but after 4-5 yrs, u kinda settle down a bit. guess she wasn't the settling down kinda girl. yes, i am childish haha... i find it boring if a girl isn't somewhat childish SOMETIMES. i don't regret anything, everything happens for a reason. kaitou n angie actually helped me understand what's probably going on in my ex's mind. starting off on a blank sheet... u can basically go find someone else, that's a completely blank sheet right there.
guys dont mature overnight..... its gonna take at least a few years.... i hope you realize that.....and i wont say anything about it anymore...cuz its really up to u if u wanna try again orrr....move on and get urself someone who really meets ur requirements....
