Awwww now I see why you are in such a bad mood and feeling so bitter... I always try not to judge people by my first impression, and although you called me a jerk and a timewaster because I feel lonely, I see you are facing a much harder problem now. Sorry for that.
Spanish man, in my own experience, are very jealous and SEXIST. They seem to be living still in the last century... so, of course, he's taking advantage of your daughter being just a teenager, and dominating her. And in her case, if she knows you're not happy about it, she probably sticks to him also because she wants to feel she's a rebel or something? people in this age usually do this kind of stuff, you know.
Well, I hope she will go out of this blindness soon, at least she knows she has support on you and might start to take your advice. Good luck and if you need any help with the language, just ask.
