<human>: Can you succinctly summarize the text in 1-3 sentences?

We've been seeing/dating/hanging out for the past couple months after being friends for about 2 years. Nothing super serious, but it's definitely not casual...there's a connection.

He's leaving for a vacation for 1.5 months this summer. Two days before he will come home i'll be leaving for a month. 

We haven't discussed anything about where our relationship's going or what we are doing. 

I know I really care about him and I don't plan on seeing anyone else while we're apart. But i'm also not interested in defining a relationship when we'll be apart for two months. 
Just need some advice.
<bot>: Guy I've been seeing is leaving for the summer and when he gets back i'll be gone for a month. Should I discuss "us" before he leaves or just leave it be?
