Search Results: girlfriend and i are different

My male friend and I had a good relationship until a couple of months ago when he brought up the topic of how there's no unity between women and boys are always so united. I disagreed with him cause I had a different experience with my girlfriends. He was quick to retaliate with, "Oh you have no idea about the world.' I felt like he was offended and didn't want to push it further. I shifted the topic to being scared of horror movies, he said he wasn't and I complimented him for it. He then went on and on about how boys have to be strong-hearted cause their life's tougher than a woman and no matter how much of a feminist I become, this will always be a fact. I didn't even bother to argue on this but he just wouldn't let it go. After that the times I met him these are all that I experienced:

1. Pointing out my lack of experience in things, again.
2. Talking about my lack of skill regarding a language.
3. Mimicing my hand gestures in a mocking way.
4. Trying to scare me as prank and imply that I am a scared little baby. Basically treats me as if I am his junior.
6. If I say something good about myself gives me the glare and questions it.
7. Tried to delete my YouTube app off of my phone because my screen time was 2hr 7m long on a weekend.
8. Would make a big deal if I make a mistake and needs to say it to everyone so they are pissed with me.
9. Would help someone else out with their lack of skill in something but wouldn't help me with the same and lets me be.

The weirdest thing of all is his desperation to prove that he is strong and I am weak. I don't get it, no one ever called him weak (in fact he's adored for being smart and efficient, I am the one who gets perceived as naive and immature) but lately it's like he's obsessed with me and belittling me every step of the way. What's worse is that I am the only one that gets targeted for all the flaws and fears the rest are have their shortcomings without judgement. What could be the reason for this bullying?
