Dear Birthmom

I went looking for my birthmom in 2013, before my dad died. I found out her name in May, a month after he died, and I wasn't able to share that with him. We met later in 2013, and we looked everything alike. We talked the same, we joked the same, we even had similar glasses. We talked for about an hour and then we were done. We exchanged emails and after a week, they stopped. She had told me, "you can't scare me away that easy", but oh how easy it really was. So now, in 2016, I am emotionally stuck; I'm stuck on whether if she tried to attempt communication again, would I let her? She gave me a birth necklace when I was born and I don't feel like it belongs to me. I want to send it back, and I think that's a good idea...
