Most Helpful Girl
The writing on my wall and all here, dear, is telling me that your "EX" doesn't want to be in anymore Real Relationship nor hooked a the hip and also it Appears... He wants a bit of sweet cake and Eat it two, you could say.
With this, he feels you both can be friends on Facebook and at the same time, which he expects you Not to Mind, he can be friendly with Other girls and this will be a happy ending to your own sad story.
It's your call, your choice, if you want to go on this way, always feeling upset and This 'hurting my feelings.'
If you feel you Know it is a raw deal, end the madness and the sadness and delete him from Facebook and carry on. I do not believe things will change much except maybe one day, should some Other 'good woman' come along, he will change his stats To... In a relationship.
My own Newsfeed reads this one cannot be trusted and you shouldn't set yourself up to be Hurt all of the time.
Good luck. xx
