When Your Boyfriend Loses His Lover

I sit with him. His head is bowed and he looks tired and sad. If tears could leak out of his eyes they would. But my boyfriend has been trained not to cry although what he does when he's alone listening to his favourite love songs, even I'm not privy to. It's heartbreaking when someone who is so optimistic, so full of boundless positivity and who brings such joy to lives through his music, is in a pit of numbed nothingness. But it's not my heartbreak I'm concerned with, it's his.

In an open relationship you have experiences which are a rarity in other people's lives. You welcome jealousy as a teacher. You challenge what a relationship really means. But the questions that are asked and answered in the polyamorous literature rarely cover the topic... what to do when your boyfriend is grieving the loss of his lover.

I'm projecting of course as I always do. He's a 'coper' of the reasons I love him. When we met he said about my baggage...

'Don't worry darling, I can handle heavy.'

He's always been the dependable one.

Perhaps he doesn't feel what I feel, to the extent that I think he's feeling it. I think he's feeling what I would be feeling. But oh.

If it were me who'd broken up with him, I'd have some anger, some justifiable explanation of why he was wrong and I was right. But it's not me. I have no anger, no justification. Nothing to water down the sorrow I feel. I try and counter with some useless platitudes like, 'Well you'll find someone else.' Or 'Why don't you go out on the town with your mates?' But in the end, I just keep quiet and listen.

'She changed. Here one minute, the girl who was brimming with love and then her heart switched off. This girl I don't know her. So it's not her now I'm grieving, it's the girl I met. We were so happy.'

I know. I saw them together. It was a whirlwind of passion, tender moments and the look I haven't seen on his face since - well, we met all those years ago. He lost her. And we lost our dreams. Love with that depth doesn't strike every day, every month or every year.

He speaks of her. Of memories. Of what-ifs. Of his confusion. I try my best not to think guiltily about my own lover, my other significant other, sleeping in the bedroom. This heartbreak is his alone. And I am the lucky one.

But I miss her too. We are still friends, supposedly. And yet everything has changed. She's not coming over every other day. Her laughter doesn't sound in the kitchen anymore. We have no exotic perfume traces on the sofa, the bedsheets or my clothes that she tried on and were three sizes too big for her. I miss her smell. After 2 months, it's all been scrubbed away through the normal wear and tear of life. I listen to the playlist they created on spotify, when they were still in love. Addicted by Avicii. Happy by Pharrell Williams. I've Got You by Marc Anthony, the last of the great romantics in company with my boyfriend. I wonder how many times he's listened to it. How many times they made love to it.

And I cry for him.

It would be easy to play the drama triangle. To see her as the girl who trampled on him. But that's not how it happened and besides, it does no good to think that way. It only heaps the burning coals onto a situation that's painful enough.

I don't blame her for her change in heart even in the moments that I see my boyfriend lost and unhappy. Our lifestyle is after all, difficult... extraordinarily joyous but comes with a heavy dose of rejection from society. Was it that which made her heart switch off? Was it the realisation that she was monogamous after all? Even she didn't really know.

So she left. We plotted and we planned in the height of summer, and we were all the unhappier because the world was so glorious. Because when you've broken up with someone, there's a hole that left behind. And all you want to do is fill it. The response from those who didn't understand was

'Cheer up, you've still got one girlfriend left.'

But the hole in his heart was shaped like her and only she fitted in it. I didn't. That hole, that wound had to heal. It was bleeding and I didn't have tissues big enough to clean up the mess.

Then a month later he said,

'I guess I'll throw her toothbrush away then.'

And I nodded in reply, breathing in relief and sadness. It was over and she wasn't coming back.
