It’s complicated?

So my boyfriend of almost 2 years just broke up with me a few weeks ago and it’s been really hard. I was so in love with him and genuinely thought I would marry him. He’s in the military and didn’t wanna deal with the distance right now. On Wednesday, he found out he’s being stationed in Japan starting in January, so we talked (texting) about that. It was pretty much the first time we talked since the breakup. We ended up talking about just small things for a while but then eventually made plans to meet up and actually talk about us and everything else when he gets leave for Christmas. Then, things got sexual and we made plans to hook up as well. I want to do both of these things, but I’m worried that it’s gonna lead me to get my hopes up only to be disappointed and depressed once again.
