For the motorbike... you are over reacting.
For the rest i think youre going to have to let go of thinking hes going to be a good father, hes not. Stop pressuring him, if he doesnt want to but feels forced or guilted into it, its unlikely hes going to be nice about it, your child will sense he doesnt want to be there.
Let him make first contact, children are resilient. She has you to be consistent, you make her feel safe.
Age appropirate you can explain to her that some people do not make very nice choices and not everyone knows/wants how to love and be good parents but its okay because she is loved so much by ypu and that is enough. Do not ever lie. Dont bad mouth either, because she will then feel like she has to take sides and thats unfair. She can then process the situation much better, she wont expect much from him and wont be let down.
Dont worry about it. Your daughter will be fine. Just leave him to it, its your responsibility to be a mother and his to be a father, not your job to chace him.
Courts will make dates for contact, so every saturday or every other weekend, dont count on him or make plans those days, he probably wont turn up. Most importantly do not react to him and text abuse ect, he will enjoy it. And make a plan of action for what to do if he doesnt turn up, dont overcompensate with your daughter out of guilt, but it would be nice to have quality time. When older obviously you will have to ask her how she feels, validate her and listen and then leave her to feel those shit feelings for a while before returning to make her feel better. You do not want her to act okay or hide feelings, she needs time to talk about them, to be validated and then time to feel those feeling, not to have someone chase those feelings away and sweep it under the rug by instantly trying to cheer her up.
Also dont count on that letter from solicitors either. He sounds like an idiot and an idiot would say shit like im seeking legal advice but actually never does.
Please stop texting him though, its obvious he enjoys it and sees that it hurts you that he doesnt want to spend time with daughter and also that you have no respite, all your doing is making him feel good that he continues to control how you feel and what you can and canot do because you always have baby.
Just stop responding, unless the text reads can i ses daughter date and time do not respond. Be the strong and mature one.
Also validate your own feelings, you dont need anyone ever to validate your feelings especially him, if you know hes a shit dad and shit partner and that hes donr xyz then you dont need anyone to apologise or explain it to you, you know what hes done, hold onto that truth, validate yourself and move on, and accept also the likelyhood of him staying in your daughters life is slim. Hes never ever ever going to respond to your text accepting and take responsibility and accountability, addmitting to being shit and wanting to change, thats a fantasy.
