How to understand a leo man's HEART

Just really curious to understand bcuz I like him and the chemistry is there but yet I don't want it to be me giving "all of my self" emotionally,mentally or anything else! Some opinions is welcomed 🙂)

My observations of Leo's up to date.

They have heart! And I don't intend to make it sound like they are
particularly "good" ...

I mean, they're very intense about what they do, what they like, what
they want. If you really take a good look at a Leo, you'll notice
that behind that calm demeanor.. or even for the goofy ones haha ..
there's a fiery soul. When they are emotionally invested, they truly
have their hearts behind anything that they do. They can be
dramatic, impatient, restless, angst-ridden, impassioned..

They don't hold back when they love. They'll wear their hearts
on their sleeves. Very generous and deeply loyal. Just don't
take advantage of them and injure their pride because they
will abhor you.. forever.. literally.

The Leo's I have known are very giving.. but to be fair.. the only two
I know aside from those who were romantically invested in me are my
brother in law and an old friend. Both were very romantic and giving.
