@OP,
Ur even lucky he accepted u back. D worst u can do to ur man is date another and start coming back.
2ndly, d aspect of him hitting u isn't good at all but if anybody tells u he'll not change is a big lie. If he's educated he will. That same girl saying he'll nt change is experiencing sometin worse. we women r often provocative. Its even beta he did it now n repents than after marriage.
Seriously in reality, sometimes a man should give his woman one or two slaps to prove that he's a man and not a weak toy. But he shouldn't over do it b/c me I go spray hot peper for him blokos if he cross boundary.
Just enjoy for relationship and do not let some caricature chidish advices on nairaland or friends tear u both apart.
3rdly, try to show him more love thhis time around. Men love to be pampered. I've been with my hubby for years now and he wz my first and only. He even did worst, yet we r happily settled. U dnt need to test a thousand men to chose. Enjoy
