I'm going to try to give you a little bit of a look into her perspective, coming from a 19 year old girl.
My dad is divorced too. He has always chose women over me, and this makes me NOT want to spend time with him. Even though you don't believe you do so, your daughter probably feels like you are ignoring her for your girlfriend. I mean, if you work 12 hour shifts AND see your girlfriend a good bit, there's no way you're able to fit in an adequate amount of quality time with your daughter as well. The times you are probably spending with her are spent being angry at you because of the girlfriend. Not to mention, divorce was probably REALLY hard on her if she was 17. She was old enough to fully understand it and get full negative emotional side effects from that. If your oldest daughter is 22 and you just got a divorce a year ago (and your daughters were conceived inside of wedlock) then you must have been married for at least 23 years. And you were already dating 5 months later! Of course this is going to make her very angry towards you and not want to have anything to do with you, much less talk it out. You didn't give her enough time to heal from the divorce and you already brought another woman into it. On top of that, the attention that is supposed to be devoted to your daughter is taken away from by the woman. I really just do not think she was ready for this new woman to enter the picture. It probably makes her feel like you didn't really love her mother if you were able to move on that quickly. And another thing, I loved quality time with my dad (before he started putting other women first) and I would still be on the computer talking to my friends and stuff. Teenage girls are going to do that, it's like our life. The important thing is that our dad is there with us, talking to us as we do all the social medias.
Not saying that any of this is valid or correct, but just letting you know what is most likely going through her head. Hope I helped!
P.S. She might benefit from seeing a counselor to work through the divorce.
EDIT: If you take away her phone and car, then she will definitely resent you more!
Second EDIT: To the people who are giving this thumbs down, I'm trying to tell him HER point of view, I'm not saying it's a good one or that she's right!! Geez.
