Maybe you should get checked for ADHD yourself because you mentioned being overwhelmed and thats the exact same scenario I experienced with an ADD girl I was messing around with.
Overload is a very common symptom of ADHD. Not only that but your manner of writing is very ADHD as well.
At the time I was only concerned about getting her in bed and had no idea what ADHD is. 2 years later got diagnosed myself.
We tend do be attracted to other ADHD people. Get yourself checked.
As to wether or not you should be together, I wish you do reunite and create a happy relationship.
