I assume you have put me on ignore already, I don't care either. Likely you will not want to hear this either.
You have a broken heart... and I am sorry for that but really - you were there for the breaking. You have to take
some responsibility for how you feel now.
You had a TWO month relationship/dating phase and after that whilst
you swore lifelong love and allegiance
she went off to do her own thing for well....a really long time and now forever..
Each of you had a choice's and needless to say you don't like hers but she is still thoroughly entitled to date and live however she wants to and with whomever she wants to. As for her re-establishing a relationship with her ex.. that is also her prerogative. You have to stop thinking like her 'keeper' - you are not and being a 'keeper' is unhealthy and exhausting.
At least now you know where you stand!
If you thought as much about your own health, happiness and loved yourself as much as you proclaim to love her - you would be one fantastic human being. Why not start doing that?
She may have been a bit shabby around the edges with returning belongings but I think you could have retrieved them at any time and it was in fact you who chose not to make positive steps to get them. Possibly you wanted to have a plausible reason to see her again?
Ask one of your mutual friends to go pick them up for you and be done with it.
@solemn93 we've all been there and probably had at least as much or worse done too. Time to invest in yourself and get on with your life, be successful and happy with yourself rather than some unsubstantiated illusion.
I always think success and heaps of it is a great remedy for the heart! :)
