<human>: Hello /r/Relationships,
We have been dating for half a year and are very serious about our relationship.
I am pretty torn right now and I am desperately seeking for advice. When she told me this morning I could not control my feelings and started crying because of the fact that I can't afford such a travel and thus can't propose her to travel with me. The fact that she wants to travel with this guy, who I know had feelings for her makes it worse, even though he has a girlfriend himself. At first I just told her I was sad and that I do trust her and she can go, but the more I think about the more uneasy I feel. I mean, why does she even need to go there? Why with that guy? I don't want to forbid her from going, but I feel like I would die in those 3 weeks she's away. Furthermore thinking about this issue makes me mad at her for even proposing this travel. I need to hear other perspectives about this, before I confront her later this evening. I really don't want to hurt her feelings, because I tend to say unfair things while arguing with her in the past. So please help me!

Provide a brief overview of the text.
