@The new girl,
I take it you are very young.
I didn't read a single thing you did that you needed to apologise for. To me your behaviour (other than the apologising) was normal, and rational, and his 'hurt' wasn't.
Any woman who provided a similar story, I would tell the run the other way, and hard.
The alternative often includes:
- ongoing emotional & psychological abuse (this one already shows a staggering amount of evidence)
-the destruction of your self worth
- the reliance on short term highs (and the larger portion of down periods)
- the loss of long term happiness
- a life controlled by your partner: your movements, who you can be friends with, when you can see them, why you are a slut etc whenever you want to see a male friend (this isn't the case, but such men want you to believe that it is)
- the loss of friends / separation from family members...usually the ones that try to warn you off such a 'man'
Often, such character traits can lead from emotional/psychological abuse, to overt control, to physical violence, with the woman slowly lead deeper and deeper into a feeling of powerlessness.
Few women get into a relationship where their boyfriend beats them on the first date, or 2nd, or 3rd etc (perhaps...really perhaps...a hopeless drug addict might). Sometimes it develops over months, sometimes over a couple of years.
If you still don't comprehend, start reading examples from Domestic Violence support sites, where women explain how they were drawn in.
