@Monkey1,
Monkey.. Is that how you feel. ?
It's very hard to get back with an ex.
Can I ask why it ended the first time? And how long you were apart?
I think, when we haven't found "the person" we want to spend the rest of our life with, we tend to go back to our past anything that makes us happy, if we are not in the place where we want to be within our lives, not ready even.
She is single, in her mind, and her trip is something she has been waiting for, in her life of haven't found what she is looking for, justs gets comfort with her ex... No Clamidiya or something.
I think that she will not cheat actually. She just gave you a message, you are her safe sex partner... But, she is looking.
I am sorry but that's how I feel of this. If you were loved? You'd be going soon, don't be a "settlement" of not wanting to be lonely all people are capable of doing this, when lost, trying to find, want so much and then settle and use... to get that feeling, whilst looking.
That is what I see.
She can't take you? And there are couples? You ain't there when she gets back.
Move on. You deserve better.
