Anyone with experience of long distance relationship?

My boyfriend is looking for some internship abroad - he still doesn't know where he will be accepted.

We've been together for one year and we had our amazing moments as we had hard times.

In a few months he will be leaving, and I'm not in the position to go with him due to my therapy and economic situation - I'm unemployed.

Now my question is how do you cope with jealousy? And arguments if there are any?
