Is it normal i fall in love with the anime girls ?

I fall for singers/actresses.

Yes, you should profess your love to this anime before she finds another man. Be confident, take the initiative! Who knows, you may end up married with your own little anime' s running around the house.

Its definitely not healthy to love people who arent real dude

It's normal, that's their purpose. They are idealized versions of humans. And anything is possible with imagination.

But don't overdo it, don't let this take over your love life/potential love life.

It is normal to grow feelings of affection for well-written fictional characters. I did when I was younger too. It's a sign of loneliness or a lack of real affection in your life. I'm not saying you need to go out and get a GF right away, even an ordinary friend fixes the problem if they're a good buddy to you.

Or maybe you're not lonely and you just have difficulty separating fiction from reality in your mind, who knows.
