Advice: Don't date people with the same interests as you!
Seriously just don't. Should that relationship ever end, your life will feel even more ruined. My ex and I were basically the same person when it came to interests and hobbies (the exact opposite in other areas, though). We loved ALL of the same things. Now all of those things are ruined for me. I know I loved those things before him and I should love them after him, but a huge part of our relationship was obsessing over the same things together and that's how we even got to know eachother. Now, all those things remind me of him. Or they make me sad, because I can't talk to him about them. I lost the love of my life and he took all of my other loves with him.
