Hello! Posting this for my intj brother here... shhhh he doesn't know 
Urm....
So, Andy tests as an intj on all the tests that he's ever taken, and he's normally a shy, extremely introverted person that loves his own company more than anything in the world (the only person he talks to a lot is me and his absolute best friend tbh). So he's a very logical person, and he despises when girls are all like 'oh my godd that guy I'm so totally in loooooove' and he can always get over crushes easily and quickly, in a logical way.
Until he met her.
duh duh duh, I like suspense
So anyways: He started uni and met a female ENFP three years ago. They clicked instantly and he talks with her a lot, constantly laughing and stuff. So my brother finally got the balls to ask her out, and he's so smitten and helplessly in love it's as if he has changed personality, he's now much more talkative, wanting to spend 24/7 with this enfp, planning a future together inside his head, constantly doodling HEARTS on pages ._. I'm beginning to wonder if the shy introverted boy has ever existed... Also, Andy is a fan of the awkward pat hugs, you know the ones that some intjs give, freeze up and goes rigid and does that tyrannosaurus rex arm thing? But with this enfp he holds her so tight and it's a proper hug, bodies close and arms tightly wrapped all the way around. He constantly wants to hold her hand and CUDDLE. CUDDLE. this is the guy I grew up with that blushes at handshakes (not really, thats an exaggeration but anyways...) He's absolutely smitten with her. Also, Andy normally criticizes girls a lot, and underrates them normally, but now he constantly fanboys at how beautiful his girlfriend is... he's behaving in a really, really illogical way right now and it's scaring me. I'm normally the one who falls too hard and he's the cold one that tells me to stop... He will literally do anything to keep his enfp happy, he's also very, very overprotective of her, driving her home etc. He runs across roads and stuff holding this enfp's hand... without looking. He's also more spontaneous than normal, almost behaving like an isfp! D:
So after that ramble (sorry) I have 2 questions:
1) Is it possible that my brother was never an INTJ to start with, but locked his true emotions in and he's actually and INFJ/INFP/INTP or something?
2) Have you (as an INTJ) ever fallen this hard for someone? He's basically a lovesick puppy right now, behaving as if he can't live without her etc, he missed her so much when she went on holiday that he cried...
... Or have you witnessed an intj like this?
Maybe I'm just really inexperienced with INTJs and they all fall in love like this or something? He obsesses over her and he'd be a stalker if she wasn't his girlfriend...
Disclaimer: Don't get me wrong, I know INTJs can feel deep intense feelings, but I've never witnessed it first hand, is it common? and please share other stories like this, an intj in love is so cute ^_^ and adorable when I tell my brother than he's in love and he tries to deny it with a blushing face.
