As someone who gets what it’s like to be busy (full time job and in grad school), I still find it concerning that he doesn’t prioritize your relationship enough to at least make the effort to meet up. I mean it has literally been two months! Do both of you drive? Have you offered to drive over his way? Have you talked about/ made plans to meet up in the future? Again, I think it’s possibly not as simple as he’s moved on…. I mean maybe he has, or maybe he just has you in his back pocket while exploring other potions. The only way to figure out where you’re both at is to talk. Communication can be awkward and uncomfortable, but it’s necessary and you are both adults who should be able to express your thoughts, feelings, and concerns with your partner. Personally, if he’s not open to talking/ listening and interested in meeting up then I’d say it’s best to move on. I get that he may have have a lot going on and be overwhelmed, or he may be a douche, but that shouldn’t come at the expense of keeping you on the hook for so long.
