What do i do with my friend and her controlling boyfriend?

well ma friend got a bf and i was rlli happi for her. her uva mates didnt seem to want em 2geva, but i always sed they were gd 4 each uva. whenever she complained bowt him i tried mkin her see sence, telling her he was a gd guy. but then her complainin got worse, nd she still went bk to im. nyway she had a friend (guy) who she tlked to nd he got jealous so he sent her sumit to hack her pc nd wtched wht she was doin. she found out nd still forgave him. but then he cheated on her wiv anuva girl nd they split up. For a week "/ Nd now hes sweet tlked her bak. But the fing is hes rlly controlling. How he gets her bak afta tht is unbelieveable. Hes always puttin her down, saying shes in bad moods, her hair styles not good, dropping her hand infront of uva ppl as tho hes embared. But she cnt see it. I tried makin her see but she fell out wiv me. Where both m8s now nd i dnt dare bring it up again, cuz shes gunna h8 me. i just dunno wht to do.
