Mourning for what could be?

I feel embarrassed to have gone as far as register an account here, and write out what seems to be, really, a small problem. "Mourning" seems too strong a word.

I've met a lovely girl at the fitness camp I attend twice a week. I've never seen her outside of class, but we have strong, mutual attraction. However, I plan on leaving the country in two months, and because of other circumstances, getting to know her at all outside of class seems impossible.

So, I won't get to know her, a potential friend or partner squandered by circumstances. Nothing new, an old story-- but I don't know why it bothers me so much. I knew from the get-go that any potential for a relationship with her would not work because of my future plans. I suppose it bothers me because only tonight the hard truth of it has sunk in.

I don't really have trouble meeting girls, and although the future seems as uncertain as ever, I really do have my life in front of me. But this girl and I have really clicked. It saddens me knowing that I will not explore this potential.

But c'est la vie. I have no reason to complain, and if I got to know her, perhaps it wouldn't work out. Believe me, I never search for a "completer" or soul mate or whatever. I do believe that everything we need to have a happy life, we already have in our minds. I've read a lot about Marcus Aurelius lately, I love his work:

Very little is needed to make a happy life; it is all within yourself, in your way of thinking.
Marcus Aurelius

Accept the things to which fate binds you, and love the people with whom fate brings you together, but do so with all your heart.
Marcus Aurelius

You have power over your mind - not outside events. Realize this, and you will find strength.
Marcus Aurelius

Wise words, but living them presents challenges. Nevertheless, I just thought I'd post these thoughts here. I'd appreciate it if someone could check in, maybe. Please write constructively, I know forums have a reputation for teasing and trolling.

Thank you, and good mental health.
