Hi art.chick! Glad to have you as part of our scuba family!
Your story hit home hard so I thought I'd trot on into the discussion. Sounds like you're married to a scuba-Nazi. (Oh, by the way I tend to give honest answers to questions, please don't take offense) I dated an emotionally abusive guy for 2 years and before I give any insight I want you to think about a couple of things:
Does your husband yell at you on a regular basis? Has he ever drawn back a fist like he was going to hit you?
Can you do other activities together without problems? How does he act when participating in an activity that you are good at but he is not? For that matter, will he even participate in an activity where this is the case?
(I don't want answers, honestly answering to yourself may help you solve your problem)
Your husband's behavior is unacceptable. He is the one who looks small when he yells at you and makes you cry. My comment to him: "Oh yeah, takes a big man to make a woman cry, aren't you proud of yourself? Go brag to your mom ( 'guess what I did today! I yelled at my wife until she cried!') loser!"
I too am an instructor candidate and if I treated students like he's treating you my instructor would give me a dose of my own medicine!
I don't know how long he has been diving so I'm going out on a limb here. If your husband is all sweetness when you aren't diving then maybe the concept of being an instructor subconsciously scares him. Remember, if he screws up and someone dies the law is going to come looking for him for an explanation. Even if one of his former students dies 2 or 3 years after the last time he saw them he is going to be grilled about their training. That's pretty scary when you think about it. He may just be trying too hard to do everything perfect and he's expecting perfection from you. When things don't go his way maybe he panics a little about what people will think about him when they see you deciding not to dive or crawling on the beach at the end of the dive. Like Northeastwrecks said, it sure beats falling! You aren't a bad person, stop giving yourself such a hard time! Try telling him that your decision to skip a dive is no reflection on him as a buddy, you just don't think you are up to the task and you don't want to endanger both of your lives. If he really wants to be an instructor (or a good diver for that matter)he needs to learn to accept "let's abort" graciously whether he's given a reason or not.
If you think about it and find he's a jerk at other times then it may be time for some professional intervention. Go for yourself if he won't go with you. You need to see that you are not his problem, you deserve to be self-confident in life. If he's just started this since you lost your job, maybe the decrease in financial security has him stressed and acting stupid. Maybe your stress level is affecting him, you sound like you aren't too happy about a weight gain, job loss and another event. Are you snapping at him sometimes? Take a deep breath before you say something and ask yourself "How would I feel if he said this to me?" Try stepping back and looking at your situation from a positive angle. Maybe this is your chance to get your dream job! If you're not working and you're not happy with your appearance try going walking for 20-45 minutes a day (if you're not working you can find time to walk). Exercise clears the mind and can relieve stress. Walk as fast as you can and visualize leaving your troubles behind. BTW, if you keep that up 5 days a week for six weeks you may leave some of that weight behind too!
I've rambled on and probably ticked some people off (wouldn't be the first time) but I've given you my honest assessment of the situation given the limited facts provided. I wish you good luck and would love to know how you're doing. You are SOMEBODY, never forget that! If you're ever in Ohio, look me up and we'll go dive or maybe we'll just go to the dive site, have lunch and take a nap while catching some rays, doesn't matter to me
