<human>: Summarize the given text in a few sentences.

We've been dating for just under 2 years, and tomorrow my BF is leaving for Europe for a vacation for a month.  His parents (who don't approve of our relationship) bought the trip as a gift for him for college graduation, and only told him about it two weeks ago (that's a whole other story!).

We live together, and this will be the longest we've been apart since we started dating.  I thought I was going to be fine with it, but the closer his flight gets, the more depressed I feel.  He's going to have minimal cell service (because it's expensive to call/text), and some of the hotels he's staying at won't have wifi.  When he does have wifi, we've got Skype set up to talk to each other.  Does anyone have any tips for being apart for a month like this?
<bot>: Boyfriend of 2 years is going to Europe for a month, I'm not sure how to deal (healthily) with being apart for that long.
