<human>: Oh boy, where to begin. 

I met this ex 3 years ago on study exchange in Scandinavia. We met randomly at a party, started to hang out and were dating not two weeks later. Our relationship was really intense, but going really well, until the age old problem of exchange student dating reared its ugly head: I was going to leave the country. 

We decided to break up (or, more correctly, he decided to break up). We didn't see each other for 8 months, but kept contact, updating each other on our lives but also saying how we missed and still loved each other.

I went back to the country after those 8 months for a summer job. We were really happy to see each other again, and for a while all was well and it was just like before. However, things escalated. My guess is it was because it became really intense again but we were still faced with the difficulties of being together, being from different countries and all. 

I did something I am really not proud of when I was drunk and he ended up saying he never wanted to see me again. He apologised later, saying he didn't mean it, but it was a hard lesson for me about my own behavior, I was embarrassed and realised we shouldn't see each other for a while. 

Fast forward two years to today, we never saw each other again.

I am now in a relationship of nearly two years with another guy (I met him shortly after I last saw my ex). The relationship is mostly good, but lately we are in a rut and things aren't optimal. We had a talk about breaking up, but decided we would give things another try.

Imagine my surprise when the Ex suddenly contacts me on Facebook. He said he had been thinking about me, started reminiscing about the good old times and ended with telling me he missed me. 

Ever since, I cannot get him out of my head. I am turning here for a new perspective on things, remarks, advise, tips, whatever. I think I am starting to convince myself I am actually missing my ex...

Can you condense the text into a few key points?
<bot>: Ex contacted me after two years of radio silence. Current relationship is not doing so well, and now I am really confused.
