Wow I feel like I just wrote this myself!! I am in the same situation a 4 year relationship with someone who would never change… Until we broke up and then he changed into everything that I always wanted. And of course we maintained contact and we’re both on Facebook and we were going to try again until I noticed on Facebook that it appears perhaps he has been seeing someone else.
So like you I spent 4 years helping him become the new and improved model for someone else. So I’m also curious to hear what advice anyone else has on this. Oh and as an extra special added bonus we both took new jobs in new cities – so I relocated and am pretty much completely alone in a new place. Oh well. Just tired, sad and lonely 🙁
