“He contributed very little to the relationship”
Well you said it !!! You are not flawed. You are absolutely fine and enough in every way. He simply did not feel it was right for him – and therefore you had a lucky escape in a way !
He also sounds a bit cruel in the way he delivered the message. “Wasting my time with you ” ?? Eh… really ? Well I think you could get out with friends, do all the things that you deserve – get a massage, get your hair done, treat yourself soooo well.
Then cry, sit with the discomfort and the saddness when it comes. Breathe and after it softens – let it go… and repeat ! Keep feeling it and letting it go. Plan nice things for you. You will be ok, and u will have lots of joy ahead.
Sending healing. Xxxx
