<human>: Give me a shortened version of the text

Throw away as the friend I'm talking about reddits sometimes. 

I (f) have a male friend(40) that I've known for about a year, during this time he has had a girlfriend - she is quite nice; if not a bit young (27).

They broke up about a month ago and when I asked the reason (they seemed well suited from the outside), he essentially said she was a re-bound, that he "couldn't give her what she wants" (whatever that means), and that he needed time and space to be on his own. 

He had a previous girlfriend (I never met) whom he dated for about 2.5 years who by all accounts was an alcoholic and verbally/emotionally abusive. He broke up with her last July and then in about 4-5 weeks began to date the 27 year old who he was friends with. 

I felt too intrusive asking him that's why I'm here asking you all. 

Why did he stay? My own mother spent years being physically abused, I understand why she didn't leave the marriage (foreign country, unable to speak the language, no money, 3 kids etc).

But he stayed in it for so long and they fought a lot and constantly by all accounts. Even the GF before her (I think he lived with her) was also an alcoholic. I obviously don't know all details. 

Maybe because of what happened to my mother I'm less tolerant of abusive people. What I don't understand is he stayed for 2.5 years with an awful abusive women he calls "cunt", but at that the first chance he 'jumped ship' with this new girl (27 yo) who he even admitted was the best person he'd ever gone out with! 

I'll admit I was interested in him at one point but I don't think so now. But how long does it take to get over something like that? How much time and space do you really need to think about a horrible person - esp when he was with a really nice girl (that poor thing, after a year together the breakup really came out of nowhere for her!).

Its all very perplexing!
<bot>: A friend recently broke up with "the best girl hes ever been out with", because he still isn't over his abusive ex. How long does something like that take?
