Op it sounds like you know you haven't fought for your dd in the last year, buy don't really want to admit it.
Or you have made some mistakes and don't want to admit it. But we all have. I did.
But there's so much to this.
My advice is, don't ambush her. If you go to the house do it when he isn't there and posts a letter. Or leave something for her. If she wants to come out and see you that's great. But turning up somewhere trying to make her come to your house, could work out well or could make things worse
If he is manipulating her and you turn up somewhere and try and take her home, she could end up hating you more and itcoumd create a very dramatic scene, which won't be good for either of you.
While everything else is going on, keep trying to make contact with her. Let her know you are trying. Because, assuming he is manipulating her, she will see through it and need you someday.
You don't give up on her, ever.
However, you do need to seriously look at your own actions and see what part you could have played in this. Because many non resident parents accused the resident parent of manipulating the child being crazy, being a narcissist, using the child as a weapon etc. When actually the nrp, hasn't been interested until the RP trip so get maintenence. Which is what this looks like. A nrp, deciding they want contact because they have been asked for maintenence.
And yes you need to pay maintenence, regardless of his earnings.
