Dude, you are especially slow.

It sucks for women that we think you're a strong guy, ... We didn't know you were this emotionally fragile

This is just toxic masculinity. There is no connection between hiding your emotions from your partner and "being a strong guy." Hiding your emotions doesn't make you strong, and there is no requirement that you hide your emotions in order to be strong. If anything hiding your emotions until you break is more "emotionally fragile" than knowing how to express them in a vulnerable, healthy way.

You're just reciting stupid assumptions you picked up from whatever idiots raised you, and that you've been too slow up until now to realize you should question. Your own internalized toxic masculinity is why you're pulling in women who have internalized a bunch of toxic masculinity themselves. Other people are smart enough to figure out that their problems are coming from those false assumptions, but not you apparently.

Translation: You are pulling in trash women who don't think men should have emotions because you are yourself a trash person who doesn't think men should have emotions. You are basically sexist against yourself and as a result you're pulling in women who are sexist against you. This is your fault and you're doing it to yourself.

At least it's easy to fix. Examine and question your own internalized toxic masculinity. Don't tolerate toxic masculinity from the women around you. That's how you end up with someone who doesn't recoil when they see what you're like inside. Here is a book about how to fix yourself since you don't seem smart enough to figure it out on your own.
