HI, I'll try to piece this together with you.
Long story, shortened.
You are worried about? Her? You? HIM?
All of the above?
Slow down and look at this from a different perspective.
Your goals in life are to:Finish school,get a good job,THEN get a relationship which might work.
Right now you are concentrating on the problem,one you (and they) are not reaching any conclusions.
Are you sure you want to go after someone who doesn't:Act trustworthy,isn't sure of any of her commitments for anyone,including herself,and has the baggage she is carrying and apparently has you along for the ride?
If you feel guilty for calling the ex,good,you should.
Now, How do you get past this problem and on the right track?
I'll be waiting for your response.
