So a regular I see is starting to act a little weird. She already has ADHD but is acting even worse. Either she is not on the right meds anymore or is tweaking. We had meet on a phone lineyears ago and she has always known is was me if we are on the line at the same time. A couple of days ago we talked on there but she was clueless it was me. Should I stop seeing her or give her time to see what happens?

your doubts seem strong enough to answer your own question my friend.

Leave her on her own.

.... can be crazy fun. Just make sure she doesn't have any of your personal information.

If so, I wouldn't make too much out of it other than to keep your eyes and ears open.  If this sort of thing has become a habit then you are best off moving on.  Worst case would be a druggie who knows too much about you; that could lead to all kinds of trouble.

The last couple of times shhe has become this way, so may I'll just have to move on. She only has my first name and burn phone number, so I'm safe there.

...but have you talked to her about this?  Is she working on leveling out her moods?

Did her phone go ca-poo-ey & she's got a really bad memory!!??
