Someone else's laundry

I am wearing a shirt that is not mine. The laundry gave it to me by mistake. I can't give it back to the rightful owner so I am wearing it. 

Not long ago it was worn by someone else. A woman. I maybe even have passed her on the street or stood behind her in line at the supermarket. 

I should be bothered by this proximity with a stranger. The wearing of a strangers clothes just washed. I am not. 

You spent the week with her in another city, sharing a bed, sharing space. You will see me tomorrow possibly. I will hug you, share your space. You may tell me you love me as you did before you left. 

I spent the weekend pondering if you ever wanted me back, would I be able to share you like a shirt worn by someone else, just laundered. Would my phyche be able to ever get past this? This use, this wearing, this closeness. 

Once in the evening you came wearing her sweatshirt. I asked where you had gotten it. It was hers. I cried. Her things on you. It hurt so much. 

You just texted that you are back but didn't invite me for coffee as you said you would, only that you will pick our son up from school. I want to die. I understand why people feel this, that they can't bear the pain and they want to jump off of bridges. I did this damage. I pushed the first domino. I pushed us down this hill. Now I am a divorced mother. We never even were married. 

I went on two second dates today. The spanish guy who owns a vespa shop in Barcelona and the Australian journalist. I like both of them for company. For an hour. For a meal. This is supposed to help, this company. 

It really only reminds me of my loss. 

How do I replace this lifetime shared. I have to trade you in for someone else's shirt? For someone else's laundry?
