I went to middle & high school with this guy and we were friends. He started messaging me on social media about a month ago but he's in the marines and stationed in Japan currently. He seems like he's super serious about wanting to be with me when he gets back to the US but I've still been using Tinder. Should I stop? I'm not sure if this is actually going to amount to anything and he doesn't come back until August 2018 but he should have a leave sometime between then.
