Thank you A8 & LLEG.
I'm not a counsellor LLEG, I have just had the benefit of lots of excellent advice over the years from my mother who is a fair and strong-natured woman and an expert at men management . Yes I did manage to change the behaviour of my ex p, although the relationship didn't last, we certainly parted as equals at least. I think that some men really are bastards whereas some are acting like one and don't realise how out of order they have become.
Glad you are looking further into your new career A8, you should definately pursue it. If Mr A8 questions it negatively, just say "It's what I want to do". Don't try and persuade him to see it your way if it's clear from the start he won't. In fact, the more you carry on, making calls, going for college interviews, getting funding sorted etc the more curious he will be and like a child I bet he will end up asking you about it if you're not begging him to listen to you any more. My mum always said that men like women who are interesting. Doesn't mean working, or career woman, but certainly a woman with her own interests that she pursues regardless. A bit of mystery also helps - don't tell them what you're doing all the time; be a bit late sometimes "Oh did I not mention I was going to be late? Sorry". (Don't jump in and tell them where you were immediately, wait for them to ask!!)
The main thing is to believe you are his equal then act like it. Occasionally question him like he questions you (this is very disconcerting but he won't know why). ie. Start up a conversation about something he does you don't like, go on about it in a picky way, then when he gets fed up, back out with "I'm just saying"... But do it subtley, ie not seeming like you're mimicking him. I would bet a fiver he will take a lot longer to get shitty than you think he would. This is because you're speaking his language and if you are assuming his role, he will assume yours, initially. That's why its a good leveller. NB: if he does get shitty straight away, and "spots" what you're up to, "Oh, tit for tat is it?" etc, that means he knows exactly what he's doing when he does it to you. This is more the sign of a bastard than someone acting like one.
Don't thank him profusely for every meal or treat as it will only serve to remind him of his paying power. Stay quiet sometimes. If you do say thanks, just say "Thanks for that" casually, as he pays. Don't go over the top. Order five things off a takeaway menu, or expensive wine in a restaurant occasionally. Be cheeky. This is not being grabby, it is re-educating him that you are an equal.
Generally the more you use the word "I" when speaking to him, the better. Make your world revolve around you instead of him. "I don't", "I won't", "I will" etc - all very powerful and will draw him in more than "You don't" etc - because they won't listen. Mean business, though. Only make statements you fully intend to back up or he won't take you seriously.
Long yawny post again from me but I have found these things useful through bitter trial and error and they have worked for me in the past.
