I used to be in your shoes too. I found a great gal, who was understanding of my "obsession". Eventually, she became resentful of the time I spent away from her, and tried to get me to cut back. I tried taking her out on the water a few times, but she was only mildy interested. Eventually, we broke up.
That was 15 years ago.
Ever since then, when a relationship began to get serious, I rattled off the same speech:
"I fish.... A LOT. No, I mean it, A LOT. Like every weekend a lot.
It's what I do. It's who I am.
It's not that I don't want to spend time with you, or that it's a reflection upon you. It's just something I need to do.
You're not obligated to like it, or try it. If you do try it and like it, great. If not, that's ok too. In fact, you can even hate it. But...
You can never tell me to cut back or stop doing it. That won't work for me, and I won't do it."
For the most part, that cleared the air and took care of the problem.
Then I was blessed with a woman who not only tried it, she become addicted like me. When she urged me to buy a brand new Ranger with all the bells and whistles, I knew I had to marry her.
Now we fish together every weekend. ;D
It's all about determining what's important to you, and not compromising until you find your match.
