I need freaking advice, i don't know what to do, new-ish lovers.

So, me and my boyfriend, have been dating for going on 7 months, this is the longest relationships
we both have been in and im
scared, cause i don't know what to do.. but he doesnt open up, like when i
say im upset, and explain all he says okay, and i don't know, like i know
he loves me, and i ask my mom for advice and she says he only has eyes for
me and its normal, but i don't know if its normal, because moms say things,
and i don't want to lose him, like you know this may seem basic
relationship drama, whatever, but i honestly don't know what to do, i just
need advice, like...gr, i don't know how to explain it anymore then i did,
theres a lot of details i don't know how to describe and i don't know

It isn't easy for some guys to open up and express themselves. We're socialized to be tough and not very emotional. I'm guessing that you're both young.
