<human>: Can you provide a brief rundown of the text in within 3 sentences?

I was recently in a LDR that lasted four years throughout college with this great guy. Long story short, I cheated on him this semester (our final semester) with a good friend here and we broke up. The good friend and I continued hooking up and we're effectively in a relationship now. The thing is, we won't put a label on it or define it because we're both scared of getting too attached when it will end in a few months after we graduate (he's from the UK, I'm from the US). I'm planning on applying to jobs and stuff in Europe and potentially the UK but there are no guarantees and we'll most likely be apart. We keep bringing it up but dancing around the subject and never come to any conclusions. I know that I probably shouldn't have jumped into something so quickly, which is why it's taken so long to define, but the fact of the matter is that we're effectively exclusive and spend a lot of our time together so not defining it at this point is just stupid and causes a lot of fighting/confusion.

On another note, he can be a huge dick sometimes. He never offers to pay for things and I've even paid for a few things myself (under his expectation that I would, which I find ridiculous). I feel like that's just common courtesy to OFFER. He also makes a lot of snide comments and when I get annoyed he says he's joking but sometimes I'm just like "dude, relax, that was too far." I get that it's his personality but he can be pretty offensive at times. 

I get that it's possible I am comparing him too much to my ex and trying to recreate a four year relationship that was pretty awesome with a good friend that won't have the same amount of time to build up. I just don't know how to separate out my feelings and come to terms with what I want and how to go about this. Any thoughts?
<bot>: Dating this new guy, don't know if I want to make it a relationship (seems inevitable), graduating soon, can be a dick sometimes (which I'm not used to)
