Well said mate a similar thing happened to me.
For many years me and my best mate always fished together, started of sea fishing and then we moved onto pike, we travelled all over the Northwest plus upto the lake district and Scotland and then we did the full circle and went back to sea fishing mostly around the Northwest and north Wales with odd trips to the east coast.
Anyway it was getting a bit much for me with two small kids and work so I moved back to doing some coarse fishing on my own and that led onto the carp fishing for me. My mate carried on with his sea fishing and is still at it today.
We are still good mates but we just don't fish together.
I'm the same like getting out on the bank on my own, gives me time to unwind and relax and I think when I'm out on your own fishing I personally put more effort and thought into my fishing. π π
