I know exactly what you mean - he bought a lot of the stuff in my house so whenever I use my coffee machine it reminds me of him, use the Firestick to watch TV, he bought it, all my mugs from holidays we went on together, pictures on the wall of our holidays, ornaments he bought me, he even bought my bloody sofa and big squishy cushion so when I sit down and relax my first thought used to be “thank you DP for making me so comfy” and it still is, but now with sadness!
He didn’t really have anything of me or mine at his house, so I’m sure he’s not really reminded of me regularly. He had a little figure of me, but I imagine he binned that. And a painting I made him which he still has. But he moved house so I hadn’t even set foot in his new space since he bought it.
That doesn’t mean he’s forgotten me at all. I know he missed me too, but I think he’s much better at compartmentalising, so left me mentally in the past and started trying to rebuild his life. I’m finding it harder, as I make strong associations with music, smells etc Even doing a specific task at a job I didn’t have when we were together reminds me of him, because I must have thought about him the first time I did it and it’s now ingrained!
If you’re tempted to go back, don’t. I had one night of my old relationship back and it’s set me back months, like I’m now breaking up with him all over again.
