Oooh, so many replies! Where to start???
Leftmy, no I was not the OW, but it is an obvious question. Dsd's DM left my DH (her dh at the time, dsd was 5) as she was having an affair with the df of one of dsd's school friends (confirmed to me by dsd in a passing comment when she was 8 and too young to understand what she was saying, I did not elicit it out of her!). I met dh about a year after she left him.
Whilst my op does focus on all I pay for for dsd, that is not the sole basis of our relationship, but perhaps where I have got to with my frustration with her. Yes I organised her prom dress, yes I paid for it, I also organised taking her for fittings, shopping for jewellery for the event, to get her nails done and her hair done. I took photos of her and told her how gorgeous she looked (and she did). I did all this because her df is clearly not going to be good at all this girl stuff, and her dm just wasn't making any moves to do anything about it. We share the horsey interest, I have one too and we ride together when I can and am at home (although often away with work).
When she lived with her DM, she was swearing at her, hitting and punching her ( age 13-14), truanting constantly, staying up on school nights til midnight watching films and posting stuff on FB so we knew what her night time habits were. We were desperate for her to come and live with us because she was going off the rails, her DM was not coping and we love her, we do. I want the best for her, as well as my 3 other dc, and not just materially. I want her to be happy. That's all.
As I am away with work so much I think she gets plenty of time with her df when I am 'out of the way'. It may not be always 1:1 quality time, but I guess that's modern busy family life.
I disagree that I cannot call myself a parent. I do not try to replace her DM, but it takes more than genetics to make a parent. I have baked her birthday cakes, put plasters on cut knees, wiped away tears when she's fallen out with friends or a boyfriend. I have told her she is special and loved, and given praise when it's due. But I think there has to be a balance. I should equally be able to say you are not looking after your horse properly, or your bedroom is a mess, or could you please hang out the laundry and not get a mouthful of abuse.
Hibble, no I don't do her laundry or tidy her room. I don't do that for my own 15yo dd either, as I think at their age they should be able to keep their own space in a liveable state (not immaculate, just not a hogs den) and be able to work a washing machine.
I think I perhaps need to sit down with dh, again, and try to get him onside. He is a very tolerant easy going guy, who just wants a quiet life without any conflict. So do i!
