Honestly...

If i was in that relationship, i wouldnt do anything to hurt my current partner... maybe odd chats about past relationships are ok but not to the extent of messaging the ex, deliberately hurting the current partner...

You also, have pointed out that he knew that you are jealous of her, but still he did continue doing it anyway...

But Shayla said, Brits doesnt want to be controlled... yep, can be true... but there is always an exception to the rule... if it is too much then it is too much...

It takes two to tango... It isnt one way...

Maybe, he's just fed up of you being overly jealous or maybe he doenst want to be controlled, or maybe he is still enjoying the company of his ex, or maybe he is just overly friendly, or maybe he doesnt love you enough, or maybe he wants his freedom back...

If he really thinks highly of you, he will respect you and be merry with you...

But it was his decision not continue your relationship...
Too bad, you might be his perfect mate...

Please be okay... I am sure there is someone out there who will love you as much.

Pray harder (it works)

Take care!
