you're not a saddo at all !
It's perfectly normal after an abusive relationship to have what's called an "anxious attachment style"- "a person high in attachment anxiety worries that a partner will not be available in times of need. An anxious person makes insistent attempts to obtain reassurance and love from others, partly because of the person’s self-doubts about his or her worthiness. Anxiously attached people are preoccupied with rejection fears"
You sound like you may benefit from counselling - is that an option for you?
I remember sitting in my flat over summer crying because my ExP didn't text back in a certain amount of time - i thought all sorts - he was with his ex, he met someone else, he was bored of me.
It's taken me 4 months of counselling to realise how these thoughts were a reflection of how I was feeling.
it is difficult for partners of anxiously attached people - it makes them feel very trapped. which is why your partner probably hung up. don't take that personally - it's a reaction to your ACTIONS, which can change. He loves you as a person, when you next get in touch maybe have a conversation where you realise your issues, ask what HE needs (i.e. what makes you feel uncomfortable?), and say you will be seeking to change this.
My thoughts are with you , its so difficult after a shit relationship!
