So I broke up with my ex about 2 years ago and I haven't seen her since.

We were in contact tho, texting about random shit every couple weeks or so.
She is dating a new for about a half a year or year or so.

Now she has to come to my town for work (we live about 6 hours away from each other) and she asked me whether she can sleep on my couch for that week.

What should I do?
