Tips for a temporary long distance relationship

Anna

I am going abroad for 3 months (leaving this Sunday) and I will not see my boyfriend in that time. I cannot imagine being apart for that long, and now that the day is coming closer I find myself in tears when I think about it. Any tips for (temporary) long distance relationships? Any tips for the moment I'll have to say goodbye and walk away from him to go through customs (the part I am dreading the most)?
