how to deal with a capricorn men ?

so i've been texting a capricorn man for almost 6 months,

we texted a lot,we knew each other back in high school but he was a twelve grader and i was a tenth grader,

and then he moved to Russia to study

and now i'm in the twelve grade and we've been texting a lot for almost 6 months,

he got home this month,

when he first came home i was in Italy for two weeks and he silent treated me for a day after i told him that i was in italy,(idk what that means)

and then when i came back from Italy on Wednesday,he came to my house almost midnight only to talk,

we talked about everything and there was no awkward silences whatsoever(?)

and then the next day we went out to watch a movie,he was different when we're in a crowded place,

when it was the two of us,he hugged me,he stroked my hair multiple times and we went to an old building and played with dog and we cuddled because it was only the two of us,

the next day we went out again,he stroked my hair,he played like a kid we talkes about everything,we laughed and everything

i was shocked because i thought he was the more serious type because he is a cap and he is dead serious everytime,

he told me that he's intrested in me and he's pretty much an open book,he talked about his family,friends,his life everything.

he even gave me his debit card pin

I'M A VIRGO ,i am worried that when he got back to Russia he'll find another one or whatever because we're not official whatsoever,because i love him and he's everything and he protects me and he took care of me

and i told him that i trust him,and he wants to introduce me to his family

but i'm in him soooo deeep but you know,Virgo analyze everything and overthinks everything

MY QUESTION ISS??

1)is he in love with me?

2)is he in it for the long haul?

3)will he ever cheat on me?

4)is there any feelings involved?
