Get rid.
If you have a girlfriend and a boyfriend, then you are cheating on both of them.
On a holiday, you would want to spend time with your girlfriend. And if she is cheating, she'll refuse to show up. That is one way to find out. Also, her weird reasons for not doing what you usually do, can imply that she is cheating.

Road trip
I don't dream about your girlfriend
Tell her the truth. If you have been cheating, hiding it means keeping secrets, and for a relationship to last and work well you need to be open. If you haven't, you have to find out why your girlfriend thinks you're cheating, whether you did something that worried her or whether she lacks trust.
then he must be cheating on you if he has a girlfriend? i mean if he likes you and has a gf then he must be cheating and wanting you?
stalk her
