Most Helpful Guy
To be honest, you should move on. You seem to be a nice guy, and for that, you should be treated better. A person who can disappear for 6 months without even saying anything is not a person you should trust, so don't make that mistake. She broke your trust and right now she's just looking for an easy target, something to take care of her while she's in a slump.
Dump her, and you'll both be left better off in the long run.1
