I have done two caminos, Frances in 2019 and Portugues in 2023. In each case I met people on the camino and we ended up "walking together." In reality some days you are full of energy and others not so much. We often left together, but after a while, one would proceed faster or one would want some reflection time alone. The agreement was to meet at the first bar in a given town for a break. This could happen multiple times a day. On the Frances I met a group of women in Orisson. After a couple of days, we had spread out on the route. One in particular seemed to be on my schedule. We kept running into each other over dinner and after a week we started making plans to meet at particular stopping points. This carried on until Burgos. She wanted a rest day, and I wanted to keep moving. We still texted every day and I would let her know about where I stayed or had a good meal. After Leon I got sick and had to back track to Leon. She was there and told me of a good place to stay. After that we kept in touch with her telling me of good places to stay and eat. A few days later, I met a lady and we ended up walking together to Sarria. I had to wait a day there for my daughters to arrive and join me. Both of these women were waiting for us when we finished in Santiago. There was no romance, just people who had similar life experiences and enjoyed talking. We still keep in touch.
The Portugues was a similar story. From Lisbon to Porto was somewhat lonely. I did meet people and we would walk together and then agree to meet in a certain town at the end of the day. The companionship was very enjoyable. In this case, with different itineraries, the walking buddies changed every few days. We did all met up for dinner in Porto which was enjoyable as we shared experiences. After Porto, I walked with my daughters. Thankfully they met people on the way who they could relate to and enjoyed visiting with while walking. My friends from the Lisbon to Porto route either stopped there or walked on the Coastal while I took the Central. Some of us still kept in touch while on our different routes, which was to me as good as walking with them.
In summary, though I think the expression "The Camino will provide" is an overblown cliche, in this case it did and should for you. People walk at different paces or with distinct agendas, so it is better to just meet up with people on the way rather than try and force fit a walking buddy. In neither camino did the itinerary I planned last more than 3 days. After that circumstances changed how far I would walk or what town I planned to stay in.
