Hi Shane. I'm sorry you've been through such a hurtful experience. This girl sounds like a head case to me. A young woman who separates from her abusive husband, then dates someone, and then goes back to the ex has got issues that you really don't need to be dealing with. Watch out she doesn't try to reconnect with you to try and drag you into the middle of some three way drama involving her ex and herself. She doesn't sound like too nice of a person.

Not only is she 5 years older than you, but she's got more mileage on her, in terms of life experiences. I'ld strongly urge you to look for someone who's closer to you in terms of what they've experienced in life.
