<human>: We were engaged, a little while ago her mother came down with an incurable and unknown disease that is slowly killing her mother.  She said she wanted a break which she said meant that we split and there is a chance we get back together. Her reason was "It's better to be alone than to be with someone who makes you feel alone." 

I really can't be certain but I think shes suffering and pushing everyone away.  

I too felt alone in her company, but it stems from her behavior and tone towards me.  I don't know if me sticking around is the best thing, because I have this problem.  I honestly don't mean too but I'm inattentive, and my mind wanders very easily.  I think its due in part to a disorder I may have but it sounds like an excuse and I have trouble accepting that I can't change it as a reality. 

What few friends I have but one believe with all certainty that I just don't care.  To make matters worse is I've been very busy and also behind in my daily tasks, struggling.

I've looked inward and I'm just not sure i can change this.  Have any of you had a problem like this?  When did it change? Why did it change? and how?

Can you condense the text into a few key points?
<bot>: Gf said wanted a break, her mom is sick. want to be there for her, but don't know if I'm capable due to shortcomings.
