Learniogn new things can be fun and or life changing. However, If you asre with soemone and you love them then you will want to share an interest in their interests or atleast make an effort (just being honest).
I don't think you can change who you are, you can change bad habits, but to change you is not an ideal situation, it will just make you unhappy. On top of that, why would a partner want to change you?
It's Like football (soccer), I don't like football much, but if i met or married someone who did, I would go to matches, watch on Tv etc on occasions becuase I like it, but i would get joy knowing they liked it.
talking of bad habbits above.. can we actually change all bad habbits? I was thinking about that as I typed. what do you think?
