Onemanwoman, let me say off the top congratulations for biting the bullet and trying the square job. It takes a lot of courage and commitment, and that's commendable. I don't know you at all, but threads like yours unfortunately come up quite a bit here on PERB and I've given some of these issues a lot of thought.
If you are looking for sympathy or someone to unload on, you will get lots of that here. However, one thing I've learned is that there are two sides to each story. If you have somehow decided to become the girlfriend of a jerk or an asshole, then it sounds to me like you probably know that deep down already and it's just a matter of summoning up the courage to get out. But if your boyfriend is more or less just a regular guy (I'm assuming there must have been some reason you liked him and we are just hearing the worst of him right now), then I have a few thoughts on what you just wrote:
I have spent the last few years getting up at ten and taking my time in my day. I struggle now to wake up by 6 and nevermind how hard it is to get to bed early enough.
As someone who has worked their whole life in the square world, this sounds really bad. Sorry, but if getting up at 6 is one of your biggest issues, you might be beating yourself before you even start.
I am still doing the odd call to pay rent etc as I haven't been paid yet but why can't he stop treating me like I am a hooker?
If you are only doing clients because you haven't been paid yet at your regular job, then it stands to reason you will be able to stop after a month (ie., after you get paid from your square job). If you cannot or will not quit after you get paid at your square job, then you will either need to get a better square job, continue SPing, or learn to live with a lower income. To be really honest with you, the SPs I've met have typically not had great money management skills because they are so used to having so much money. That's why I'd suggest you take a really hard look at whether the only reason you're SPing is because you haven't been paid *this* month. Because if it's an ongoing thing, then your relationship problems (and this argument with your boyfriend) will also be an ongoing thing.
When will he stop resenting me? When do I get to feel like a real person and get credit for working every day and having such stress about being on time and not dressing too slutty in my all male office and getting respect from my coworkers who may or may not know my previous occup? What kind of man would still cause me stress through this transition? Not one who I have loved for 2 years you'd think. Is he scared now? Does he hate me for being a sp up till now? He is not cooperating and he is just doing whatever he wants to do. Still I need advice on how to fix this.
If you have been an SP for several years, it's very possible that the crowd you were hanging with then was not your typical 9-5 office crowd, and so you might be used to a whole different set of values. Here's an example: in a typical office, a girl cannot wear a skirt higher than 2 inches above the knee. And that's not even getting into the rest of it, like the size of your jewelry, the length of your hair, the amount of makeup or perfume you wear, etc. etc. etc. I'm not blaming you or anything, but I'm just saying there might be a disconnect between how you see yourself and how others in your workplace are seeing you. Maybe look around at the other women in the office and see if you are following their lead style-wise.
Anyways, that's just my $0.02. I'm assuming that your boyfriend is a regular guy and that he just didn't wake up one day and want to start calling his girlfriend a hooker. If I'm mistaken and he's an asshole, then you probably know what you need to do. Good luck.
