Search Results: how far do i pursue her

I met my boyfriend 4.5 months ago whom I find to be as career oriented as I am and shares the same interests & visions as I have. Things went well since then.

Before I go for more details I need to mention the dating scene here where I live does need you to state you're exclusive otherwise you're free to fool around. At that time I was seeing someone I had been crazy about for so long but it was going nowhere in the end. As for him he broke up 3 weeks before we met. Hence 2 weeks after we met he asked if I was seeing someone else and he asked to be exclusive, I accepted. I only broke up with the other guy 3-4 weeks after. He was well aware of it and understood my situation.

The main problem here is that I'm moving to another country soon. (He's not from where I'm from). He initially did plan to move out of the country as well next year but there was no fixed plans yet.
2 months after we got exclusive he decided he wants to pursue this relationship further and go with me to where I'm moving, which to be fair is closer to his home country. I kept questioning his decision but he was very sure he wants to do it as according to him it's not going to mess up his career etc as he was planning to move out anyway.

Lately I have been making a huge fuss and picked fights because I'm questioning his decision and I honestly think he's desperate. I'm running out of time as I'm moving out next month and I'm getting more and more anxious about whether to continue this relationship or not.
Is he desperate or am I just being paranoid? I have a history of messing up my relationship I don't want to go through that again.
