If she gave it to you then it's yours. Do as you please with it. If I may offer you one word of advice. Should you choose to return it without her asking then that's you acknowledging that she matters. That's you feeding her control over your attachment to her. Do you really want to give her an upper hand like that?
For a time I considered taking everything my ex had ever given me and sending it back to her. On a couple of occasions I was actually prepared to do it. What I did do was put all of it in a cardboard box marked "RUBBISH" with a fat black marker. It now festers in the attic. Should she ever ask I will tell her that everything went in the bin. That's my approach. It works for me. Over time you'll find one that works for you.
I agree. But first Bauie, I am sorry for the ___ty position you are in.
I have had a similar experience with some of my exBPD stuff he GAVE to me.
I really questionned returning it to him, sending him a message where I could send it (he moved around alot).
I went to the core of my being and I noticed I was self-sabotaging and my codependency traits kicked in. Because deep down I wanted to contact him and second I wanted to "show-off" I was the mature and "nice" one... .So sending it back would be the fake me and wouldn't have the right intentions. I kept it all, it was given to me, a gift... .Given out of "love/need/manipulation" at the time, still given.
No need to return it! I stayed NC and think I avoided a lot of BS. He would either be really offended giving him something back that he had given out of his idea of love. Or he would have tried to recycle, be stood up by me again, and the whole anger crap would start again.
Either way... .Not what I wanted. Boxed it and put it in the garage.
Not saying this is the same for you ofcourse Bauie... .But just realize you're trying to be the nice guy, the better person... .But thats what got us in this mess in the first place... . :'(
